Just appreciate it by stfu don’t mention the crap you’re saying you appreciate people not mentioning. It’s pretty simple.

I'll add a tip I learned, especially if you drive your hotrod a lot in hot climates and use a return line regulator: Do NOT oversize the electric pump by too much. Most of the fuel is being returned to the tank and is getting hotter and hotter as it circulates. Remote mounting the regulator out of the engine compartment helps, as does installing a cooler on the return line. But for simplicity, I switched to a pump that more closely matched the actual peak demand of the engine.

Wow Tony I haven't seen a crank driven fuel pump in 30 years. Your one of the best thanks again.

Places like AutoZone drove people away from them. My Dad dailied a 68 F100 for about 30 years Dad worked there in the 90's-2000's and I don't know how many got the split in the side and squirted fuel all over the suspension. We'd start smelling gas and instantly knew what was wrong. So he was on the fuel pump, power steering pump and alternator warranty rotation plan. Rotate them out every 6 months... But hey, they were free and he was on SSI so he had to do what he had to do...

Great feedback Uncle Tony! Keep it 100 and stay loyal to efficiency! Much appreciated!

That Roadrunner is the coolest car you own (in my opinion) and I'm looking forward to future content revolving around it.

Damn don’t see anyone talking about the fuel lines he used kinda wanted to read more about them

I ran a holley red years ago in a 78 4dr C20 I stuffed a 4.3 V6 in with a Q jet and home built HEI, Mounted it on the frame up front and worked great as a puller.

I think you missed safety on this one uncle T. An electric pump should also have a shutoff for when the engine isn't running...I always wire mine through an oil pressure switch..got to crank a little till pressure comes up to start the pump...but if you ever roll the car you don't want the pump still going.

Yes..also handy for when your "wife" leaves the damn key on ...I have bypassed your crank issue 2 different ways, one I put a relay timer,that's an additional cost that many don't find necessary but 15 sec on is nice for priming the carb then it shuts down until oil pressure comes up....the other which is cheaper is wire up just as you do then have a "temporary on" push button in the car that runs the pump while you physically hold the button down , this setup also will get you home in the event your oil sending unit stops working but either way I have grown against switch on stay on wiring since I have had wife and childern,never was a problem when I was single imagine that😉

I know it's two different things but, I love hearing the Mopar Starter whine and not start the first or second time and the third time it Rumbles to life, I am a purest and the sentimental feeling of how it was done in the 70's is pure Nostalgic Gold. My brother who is a "Mechanic" brought up the Idea of an Electrical Fuel Pump on my 70 Cuda.... after research of the Noise, connect to Battery, more Wires, Fuses, etc. it would have been a regret, goes to show a title does not mean common sense. Btw I looked up his horoscope and he should have been a bookkeeper Yup that says it all.

I ordered the Carter 4070, ran 2 tees with a check valve in between so the pump can't feed a little into the tank, and I got a momentary toggle switch to prime that can also stay on if I want, relay with keyed ignition so it can't be turned on with the truck off, can't wait to install it!

Great video, Uncle T!

My buddy built a 68 Charger with a 383. It ran 9.5-1 compression flat top pistons, solid lifter cam with flat tappets, Holley Street Dominator, 906 heads ported with Mopar Performance Templates, and of course Headers. I can’t remember the size, but the engine shifted at 7,000 rpm. This was a street strip car that probably would have run a hydraulic cam for any of our customers, but this was built by the Machinest who owned the car. The exhaust heat crossovers were blocked off, and it ran a windage tray with a deep sump pan, ran one quart low. We estimated hp to be between 450 and 500 hp. The car was also set up for drag racing with 318 torsion bars up front, an 8 3/4 rear end with properly adjusted pinion snubber. Aft Er the engine was broken in, 3,000 miles according to Mopar Performance’s DC engine Bible, we took it to the track to see what the car would run. We took it to Firebird Raceway when it first opened for some Friday Night drags. They had some teething problems there from the start. The owner dialed in a 13.0 on the fist pass because we had no idea what it would run. We estimated low 12’s but you never know. The car was runn8ng 104+ Octane boost in a mix of regular and High octane which in AZ was 91. Most everyone else gets 93 octane. I don’t know why they shorted us. The car next to us was a regular at the track, a 70 Maverick with a 300 cid truck engine in it. That’s a big six with 4” bore and 4” stroke. If he punched it out .030” that makes 306 cubes. The car ran consistent @11.0’s every time I’d ever seen it run, and that was a lot over the years at two tracks, Firebird and Phoenix Dragway in Whitman AZ. So we lined up next to him and his light went off first, ours 2 seconds later. In other words they swapped dial ins at the lights and he got our leave. The Charger launched hard, just like it was supposed to. When the driver sidestepped the clutch the car stood up, axle wrapped as far as the pinion snubber would let it moving the instant ant center towards the rear tires and then if lurched forward, hard and T by the end of the track it started to fall off. Perplexed we made a second pass, and this time, the lights were still reversed, but by mid track my buddy had caught the Mavick, u til it fell off, a bit sooner the time. We brought it back to the pits where we had towels soaking in ice water, put them on thr 8ntak runners to cool things off and began checking everything, the car had an alternator cutoff switch, but in the pits the battery was right up where it should be. So it wants a battery issue. We checked the distributor cap and rotor, and they were fine. We swapped the fuel filter next to the carb checke the 0lug wires with an ohmmeter and everything was fine. We began to suspect the fuel pump, and we didn’t have a paste with us. The next pass it was more of the same, sweet launch, catching the car next to us by mid track, but this time it fell off much sooner. We made one more pass and it fell flat on s face by mid trac. Obviously there was something wrong and it was geting worse, so we packed up and headed back to his house, and I followed in case had to tow him home. The next da we got a new fuel pump. Mechanical, and an electric that we mounted just outside the tank. He test drove it down all empty road and it did the same thong. We brought it back h9me, took and at hose and blew out the sock filter in the gas tank. But it didn’t blow off any debris, it blew the sock off the pickup tube, completely. So we drained the gas tank and put it n his street car and what wouldn’t ft there or in his five gallon tank went into my truck. Always willing to help! The we pulled the tank out of the car and discovered that it was full of rusty, and the tank sock had gotten plugged during our race night. So we got a replacement tank mounted it a made a 1/2” steel line from the electric pump at the tank all the way up to the mechanical pump, then int9 the carb. The mechanical pump had a pressure regulator so we could adjust that slightly, and we kept it at 9lbs pressure. So now the car was getting gas when it was needed, we ran a second battery mounting both in the trunk in parallel so it would lose a charge running the electric fuel pump and electronic ignition during each pass. The next weekend out saw high 11’s. What else could you ask for. A few weeks later I had an opportunity to drive the car and it was extremely docile at lower rpms with the four speed. Very 0leasent to drive, and after we sorted out the fuel delivery problems it rams very well at the track! I think we were running Carter pumps as we were factory direct with Carter, and when your paying cost plus 5% for inventory control and shipping, why wouldn’t you? The Holley I take was a used piece and it ran a thermoquad tuned for the motor.

I bought a Carter electric pump a few years ago. I don't remember which part number it was, but it didn't work well at all. I tried remounting several times as close and level to tank as possible, still didn't work... Sent my hard to find mechanical pump off to be rebuilt, and it's been fine ever since... I can't wait to see how it works for you, please keep us updated... Really like your channel, keep up the great work/videos!!!!!

One downside to electric pumps is that some of them are very noisey.

I went electric out of paranoia once... My 318 67 Dart GT fuel pump had an uncommon failure. One day the car wouldnt turn over. Ok, changed starter. New one, same thing. WTH?? Tried to bar engine over, it was really difficult. Uh-oh, time to drop the pan. Pulled the plug and the stream blew the plug outta my hand. Overflowed the drain pan by a few gallons!! The pump had completely filled the crankcase with gas til it was hydrolocked!! After dropping pan, wiping everything out, and a few oil changes back to back after just cranking engine over without spark, was back in business!! That engine was absolutely spotless inside after that!! Hung an electric pump out back and blocked off the mech hole because of sheer paranoia of a Hiroshima-like future event. I was young...🤣🤣

This was very helpful. Thank you

Great that the Road Runner is getting the spotlight on you channel! All the hot rodding and mods you do on the A-bodies and other metal is good, but the B-body Mopars RULED the streets back in the day. They were the brutes that kicked sand in everyone's faces.

Thanks for all the great info!

super helpful. I am doing this now. Geek and Son

I also put a cheap crash switch from a Ford cop car crown vic in the trunk inline with the pump circuit. That way if you are in a crash or impact of any kind it cuts power to the pump. Just hit the red button on the switch to reset it. Can be mounted anywhere in the car. Got it for $10 at the loca yard. For guys running the electric prime pump for their mechanical pump, wire it through a relay, ground the relay cpil from the oil pressure switch. That way when the engine is running (has oil pressure) the pump automatically stops.

My '66 F100/351 Cleveland has had mechanical fuel pump issues, going thru them every 5000 miles or so since I moved to an area with just ethanol fuel. The issue was the weep seal was blowing out and oil was sprayed everywhere, popular opinion is that the ethanol in the fuel is eating away at the seal. Wether this is the case I too decided to use a Carter P4070 and plan the install next week. I also hope this will solve my cold start issues I have with the truck. Thanks for the vid, it confirms I made the right choice on which electric fuel pump to go with. About the size of the line, I have 3/8" from the tank to the pump and 3/8" from the pump to the carb, is this ok?

@uncletonysgarage Can you use the 3 way fuel filter at the top of the engine with a holley blue line electric pump? My 85 c10 has the electric pump and also has vapor lock issues when restarting the engine when it is hot. Thanks

Which wouldn’t be enough,So he installed a carter gold electric fuel pump. Seems to run fine and the pump is not that noisy at all.

Why do I not have those same percolation issues with that same exact mechanical pump on my daily 71 Dart? (360LA) As long as I'm using the oem vapor return line, that is.

Great video! I could’ve used this info a few months ago when I was having fuel issues. I been through a few pumps and fuel pressure regulators. I’m now using that carter 4070 pump you got. Has a built in regulator, it’s been great!

I have a 77 GMC K25 with dual tanks, what fuel pump would be right for that? I was thinking of going electric and using the driver side fuel tank as the primary with the fuel return to that tank because I am having vapor lock problems with the carb when I have a long red light and it want to stall. Will the Carter pump be a good choice since I have to place it past the tank selector valve? I plan on using a three port fuel filter with the restriction orifice.

Uncle Tony whats a good combo for a 400 BB cam and headers 800 cfm thermoquad just trying to pick you brain on this topic i have 440 that im going to biuld but got the 400 cheap and thought putting in my car till i get the 440 done

The fuel pump just went out in my 70 vette, 350 small block w/Holly 750. So now I have to have it flat bed to a garage to put a new one in. It kills me because back in the day I was a Chevy mechanic but I'm 65 and don't have any way to do it myself.

The push pump in my V8 Vega's fuel tank quit, so rather than dropping the tank to replace the dead one, I removed the dummy plate on the SBC block and installed an old 283 fuel pump there. It pulled right past the non-functional pusher pump in the tank. That shameful setup became a speed limiter if you tried to exceed 120 mph (which was unwise in that deathtrap anyway).

Tony, your hemi pump can be rebuilt. Mancini carries kits, and although i have done a couple im not real thrilled with the chineez feeling kit, but it can be done. As far as electric on the street = noisy and and i would run some sort of oil pressure or tach signal switch

Again thank you..Guys..

Hey so I have a question. I bought an electrical pump offbrand that looks like it was suppose to be a holley knock off. Rated at like idk 140gph? some high number 14psi. I bought a holley regulator meant for idk 4.5-9psi (says only use with electrical pump but idk what difference it makes with a regulator.) I plumped it all started it up and even with 2 regulators, I used a return style and deadhead and it over powered the system and had the needle on my reader at 15psi. Flooded the carb multiple times. Do you think this was an issue of too powerful of a pump or too weak of a regulator? Also I read on some forums that the size of the return feed is important on a regulator and can change the pressure. I never bothered to reroute the return line but I did notice it was way smaller than the "feed line" which I read isnt really good but the stock pump on my sbc had a smaller return line on the mechanical pump when I first got it.

Every now and then, one of my gearhead friends has fuel issues and decides to put an electric pump in... then the REAL FUN problems start, like leaky float valves or a chinesium pressure regulator allowing a gallon of fuel into the intake.

Half the time they don't wire them up worth a crap, the wires get pinched or rub through (some people don't even bother wiring it through a fuse, just a wire from the battery, to a toggle switch, and to the pump) and the pump shorts out or they forget to shut it off and kill the battery, then they bring it to me to fix. I ask them why they didn't just replace the mechanical pump and they look at me like *I'M* the idiot.

I always wanted to go electric but heck I couldn't figure electric pumps out. I don't exactly like mechanical ones and I still can't get rid of the gas smell in my oil from almost half a year ago but it's simple and it works good enough for government work.

I love the amount of knowledge you have. The haters may not understand, but I do perfectly. THIS is what is missing in many modern hot rodders, and they also tend to lack the ability to listen and learn. I have applied things you have talked about to much more modern cars, namely a 1993 Acura Integra with a high compression (12.26:1) B18A1 with a ported GS-R head, a 1998 Honda Prelude with a JDM H22 and my 1992 Honda Civic with its D15B7 engine. Everything you talk about, still (mostly) applies to those engines. There are a few things that had to be changed, mostly because Honda engines tend to be happiest around 13.5:1 AFR under heavy load, and like to run around 15:1 to 14:1 under light loads. I have shown some of these videos to my friend with the Integra, and he even understands better what I have done with his car.

Was a shocker when a buddy put a gauge on his gto and went for a rip. Higher gears the more the pressure dropped. He added an electric in the setup and it felt like it added 30hp. (Not a gain really I know , just getting back what's lost due to issues)

In one of my 440’s! I haven’t touched in 4-5 years I gave it a refresh,maniacal pump. No matter what I did it kept running out out gas????? My god I lost sleep over this..long story short.. the fuel pump push pin was worn down and wasn’t depressing the fuel pump arm in far enough! That’s a first time for me! Just saying.

You can put a few one way gas valves in to keep the gas where you need it!

Hi there!,1958 AMC Rambler Super (pt.21) here, watched this video and learned a thing or two, but I'll have to search for videos of people who go into details about how a mechanical fuel pump can be rebuilt (if it needs to be) my 195.6 ohv six cylinder engine that's being rebuilt uses one of those really old mechanical fuel pumps and I don't know if it works, I've got my fingers crossed!

An A/C thumper pump will push 5 gallons of gasoline in about 8-10 seconds😀 through a single Spread bore Holley 800 DP 😀 but it has to be in the rear of the car or it will stop pumping. I had 1 on a 454 in a 57 Chevy years ago, it sucked up 5gals of feul in 4 gears in about 10 seconds. What a ride. Wish I still had it😔

Mechanical fuel pump for the win. I dont have an issue changing the pump on occasion. The Chevy OBS truck in tank pumps give up the ghost constantly and you have to take the bed off each time and its a huge pain. A lot easier to lean over the fender and change one.

Cheers :-)

@UncleTony'sGarage , why don't you get like a delphi pump for an lsi based engine and pull the sending unit and just put the pump right onto the outlet fuel line and push thru that and then you can mount the regulator underneath by the tank for that hidden stock appearance. Ive learned that Delphi pumps running straight and not off pulse width modulation work great on street motors

Also they will suck gas also the have a v8 swap replacement electric fuel pump for the old bronco 2s that used a pump on the fram rails and those are also puller pumps

I am about to run a 3/8 hardline from tank to pump then a -8 to filter and carb is that ok??

I just replaced the mechanical pump on my 79 suburban. It hadn't been running well for a few weeks, kept getting worse, turned out the pump was leaking internally, returning more fuel than it was getting to the carb. I plugged the return hose, which made it run a whole lot better, but it started spraying fuel out the side of the pump. I grabbed an old pump out of the shop, took about 30 minutes to install it. Hot rods are one thing, run whatever pump you want, but my stock, daily drivers will never, ever see electric pumps. I can still get gas without ethanol in it, but like Tony said, it still evaporates out of the carb if the truck sets for a week. That doesn't bother me, it just takes a few more cranks. As long as I can still get new replacement mechanical pumps, why bother spending 3x the time and labor to install an electric pump?

I HATE when you see a nice old classic and before it fires up, you hear an electric fuel pump GRRRRRRRRROOOAAANNNNNNNN . It's super obnoxious. I have a new holley 80gph mech pump and a holley 4160 carb, my car regularly sits for a week, it starts right up with one pump of the gas. I seriously don't understand what everyone is talkin about. I'm always using 93 octane, maybe it's a better blend and tony is using 87 could be worse?

@@ArdFarkable Thank you, I'm glad someone agrees. What I hate the most about electric pumps is that they're usually installed half assed, with self drilling screws right into the underbody, then plumbed right into the stock system by cutting metal lines and installing hoses so it has to pump through the old mechanical pump anyway.

Ut on my older diesel i made a fuel heater i wrapped it around my upper rad hose then back into injection pump i truly feel it run smooter than b4..my 2 cents again..

yup even OEM Diesel engines like some heat in the fuel!

I have a dodge ram d100 Drive 3 or 4 miles down the road starves for gas and dies. Should I drop the tank? Or run a electric fuel pump?

Awesome video, Tony. Thanks. You are great to watch. I always learn something from you.

A properly functioning mechanical fuel pump should not be malfunctioning or encountering any percolation issues. They will work perfectly fine on a 300-500 hp engine assuming all is well with your fuel system (i.e. no restrictions on the suction side, etc)

I went electric way back in 1995 because the 455 I built for my 70 GTO would run out of gas half way through second gear with any mechanical pump I put on it. They just couldn't pull fuel from way back at the tank under hard acceleration. it only ran mid 12s with a 2.93 gear, but that was enough to do it. I've tried mechanical pumps since, like the muscle car pumps, the expensive high volume ones, and they just can't hang with my mild 455s. The more powerful 455s that ran 11s and 10s wouldn't even make it through first gear with the mechanical pumps. I run a power wire to a relay, then to the pump so I can put a switch on it. I run all my old stuff on E85 or HE100 (that is straight ethanol with 4%-10% water in it. I make the stuff from tree sap) I haven't had any problems with rubber line going bad in the last 14 years. Prior to that running pump gas or race gas it was a constant thing having to replace the rubber in the system. Its the additives they put in the gas that is causing the problems. I won't even build a pump gas engine anymore, why bother with low compression when I can crank the hell out of the SCR and run E85? $1.85 a gallon that will run great on the street with 16:1 compression and iron heads, or $2.40 a gallon for 87 octane that has a hard time with 8.8:1 compression... 9.5:1 that the pump gas Pontiac guys want so bad needs 93 octane that is $3.98 here. Yeah I go with the cheap stuff and run the 1967-1970 small chamber heads on my 400s and 455s. Hell my daily drivers have 11.5:1 and 13:1. One of my sleeper toys is getting 12:1 with iron heads on a 400 then a couple GT45s hidden under the trunk. Yeah 12:1 with boost, no problem at all on the yeast pee.

Really? A couple of years ago I helped a guy put a 455 (big cam, high compression) in a '71 GTO. We used the stock mechanical pump for the 455 and it works just fine. He hasn't had the car on a track, but I'm guessing it runs about the same, mid 12s, maybe low 13s, with 3.73 gears. Which brings up another question, why did you run such high gears for drag racing?

Very helpful, thank you.

Maybe you can talk about the wiring of a new fuel pump. Do you use a switch,relay,oil pressure cutoff. I just want to avoid the no no's..

Run it through a relay as all motor driven devices pull more amps. Also consider using an inertia switch, you can get one cheap from a Ford Focus.

@9:28 will pushing fuel past ruptured diaphragm into the motor happen without the electric assist pump?

What if I'm rubbing 6an from the tank to the pump and from the pump to the carb with no step down in size ??

My fuel pump rn is making a metallic ticking sound an it goes faster according to rpms, atleast I think its the fuel pump its on a older chevy block. Is this something that happends offen with pumps?🤨
