How to Hardwire Your Fuel Pump With A Relay
Автокөліктер мен көлік құралдары
Hardwiring your fuel pump with a relay and lager gauge wiring is a crucial step in maximizing the output of your fuel pump. I have heard many stories of people with turbo cars running out of fuel due to their stock wiring getting hot and not being able to provide enough current to the fuel pump. This causes your air fuel ratio to lean out... Not Good.
Today I am going to show you exactly how I did this job in my 1993 Honda Civic. This method should work in any car.

Nice work, John. Easy to follow and a necessary mod for any big power car. I have few suggestions or things you didn't mention. First, you should use a bulkhead fitting to go through the top hat. It will have rubber insulation inside to eliminate the chance of the wire ever chaffing and shorting on the fuel pump assembly, plus it creates a vapor seal. You can get them for around $10 if you search fuel cell electrical bulkhead. Your install should be fine, but this is more a tip for anyone reading. Second, make sure wherever you ground the relay that it is touching bare metal. I didn't see if you sanded off the paint where you bolted the connection, but you should ideally have bare metal under the connector itself and on the other side where the nut or washer touches down. If not, it may work at first, but you'll end up with intermittent issue later. Third, this is just a suggestion to increase wiring reliability, especially in the engine bay. Get a set of ratcheting crimpers specifically designed for heat shrink connectors and a box of various connectors. The crimpers work so much better than standard and make reliable connections. The heat shrink insulation with glue adds strain relief and water proofing. Take this all as just adding on to your video of course, not criticism. I have been slowly acquiring lots of wiring tips and tools over time. Gotta spread the knowledge.
I would’ve ran an 8 gauge wire to auxiliary fuse block either in the bay or under the dash. Then send power to the pump from the aux block. This gives you the advantage of having a bunch of extra power sources instead of adding wires to the battery
Great that you made this video because there is not much to find about that topic. Good arguments in the reactions to protect the wires at the fuel pomp. So we can learn from each other. Keep up the good work and still make these kind of video's. Greetz from Belgium and a happy new year 😉
Dude well done! Extremely helpful!! I searched a few months ago for a video like this and nothing. And then you did it. Thanks again!!
Casually finally understanding some electrical concepts 2am on a Friday…thanks John😎
I appreciate you, I’m literally about to start this same process and you posted this video right in time for me to prepare myself
Thanks for helping us learn lots of useful things by uploading videon of your build. It really helps. keep it going john fr😊❤
Very good video as always. Keep up the good work 👍
Great tutorial, it really simplified the process! 👍
You should do these more! Cause I have an eg hatch as well so it helps out!
John, your right there are NO good or any videos covering THIS topic. You did an EXCELLENT job on video. Painless Wiring Company ALSO makes an EXCELLENT fuel pump relay kit. It's a great price and works just as good. I Used their brand on my 94 EG hatch for twin Bosch 044's. The DW kit you have John looks really quality as well.
Well explained. Its always better to have relays running high output components like fuel pumps / cooling fans and ofcourse the vtec solenoid
Best tutorial. 🤝🏽
John, good thoughts here. On your next install can you please use rubber grommets when going thru metal to reduce chafing/shorts.
Great content
Awesome video
Hey how did you get the AN fittings on the fuel pump cover?. can you make a video on that I wanna do the same so I can run AN lines from the tank to the front and back. Thx
Thanks John
Great video John! LY ❤️
Well played sir....well played
If you don’t have a trigger signal in case in my case for my 66 VW bug , I can wire a positive lead to a switch to turn off and on power to mimic a trigger signal to the blue wire to activate that relay correct I think I just answered my own question I can. lol 🤔
Check ECU n and look good not burnt or broken
Thanks
Thank you joung brother!
I did a k20)24 with a hell cat fuel pump I'm still on factory wiring and my k pro is throwing dtc P0005 I wonder if this kit would fix my issue?
@6:44 suppose u had a problem with your oem white green wire, and you wanted to replace all of it instead of tap into the end of it? Where does it come from?
So if I wanted to use this setup on a toggle switch would I just wire the switch on the blue wire?
You think this can help with my issue with my Honda because I change my fuel pump and main relay it didn’t want to turn on I also change my distributor also still doesn’t turn on it only cranks that’s all
Nice videos man. No one really have a easy install video for hondas. One question. For the ground coming from the fuel pump connector. Did you just attach it to the assembly that drops in the tank just like how it is stock?

Nope. The ground wire is for the relay itself. The fuel pump has its own ground inside the hanger.
i have an ep3 so i was wondering if instead of connecting the power wire directly to the pump on the inside of the tank, can i just splice it into the connector on the top of the fuel module? like cut the power in the harness and run it to the wire directly to the pump side of the harness

Yes, but then you are relying on the pin in the connector and the final length of skinny wire inside the tank to carry the current. It's usually the connector pin and/or housing that fails from excessive heat under high current loads. Your solution will work and can be reliable, it delivers higher average voltage than the factory wiring, but it can have reliability issues down the road. Look into fuel cell electrical bulkhead fittings.
Dont you need to also put a bigger wire to the ground side of pump? Love the video!
You’ve been doing all this without this? Wow
You ran the larger gauge yellow wire all the way to the pump, then connected it to a smaller gauge factory wire anyway before it connects to the pump.
Pls build video JOHN! ❤
❤❤
Still no power to fuel pump git the pump out and tested it ran good
I'm doing this to my toyota. My battery is now close to my fuel pump so my battery cable is much shorter.
Let's goo
Hi John, I would remove the Amazon link that you provided for the fuel pump relay kit. I followed the link and purchased 2, one for myself and one as a Christmas gift for a friend. The image displayed is exactly what you used in your video, but what shows up in the mail is nothing like what you used in the video. It’s basically a pig tail and a universal pump sock. I went back to the listing after realizing there’s been a mistake and there’s multiple reviews about the false advertisement and not receiving what is pictured. Wish I’d have read it first but this is one time that I just really didn’t think I had to double check since I was following the link you gave us.

@@boosted_johnyou’re welcome. After messaging the company they admit it was an issue on their end, they apologized and immediately issued a refund since they didn’t have the rewire kit in stock to send me. Customer service was really good.
RUN A VOLTAGE METTER WHEN RUNNING CAR I CAN GUARANTEE THERE MORE VOLTAGE DROP NOW THEN YOUR STOCK WIRING SINCE YOU EXTENDED WIRES AND TWISTED WIRES TOGETHER THIS WILL LEAD TO VOLTAGE DROP IN HI RPMS
#BLOWNMOTORCLUB
Please please PLEASE disconnect that immediately John. The wire running through the fuel pump lid is going to chafe on that metal and short out. This is a HUGE fire hazard! You need to use a grommet or insulated stud for this

The correct way is NOT to drill a hole in the cover. The correct way is to remove where the white plug is and put a fitting that the wires go through it into the tank.

Hi @boosted_john, is the fuse a 25amp capacity? Is the relay a 40amp? I wanna create my own, but I'm out of the States, need it for my 97 supercharged 4Runner 😈😉👉
Bruh cmon why would you drill it when you already have the connectors there
