    @@TheMrJackpinesavage Thanks for sharing your experience. Ouch. That sounds like a hot mess! As you know, this isn't necessarily something that every boat needs: It solves an inherent problem when upgrading an older portable fuel tank to one that is zero emissions (EPA-compliant) - flooding the engine (and spilling gas). If you have a newer portable fuel system, it's set up to work right out of the box; no fuel-demand valve needed. Glad you were able to work things out, and it sounds like "good riddance" was the solution for you.

    Why not replace the fuel hose since the lining has already delaminated from the inner rubber. The lining will eventually dissolve with the ethanol in the gas and clog the line.

    Question about this product. I have one on my fuel line and right now it feels like fuel isn't getting past it when I pump the bulb, could it be that this device needs to be replaced

    Thanks for the question, jungarn. We reached out to Mary Taft at Attwood Marine (616-897-2301), which is one of the nation’s largest producers of fuel lines and demand valves for boats. She said that, in some applications, certain fuel primer bulbs must be held vertically, with the end pushing fuel to the engine upward when squeezing, to prime. That has been our experience as well in boat fuel lines fitted with and without a fuel demand valve. Holding the primer bulb can help significantly and may help you with your problem. If it does not, we recommend replacing the fuel line, demand valve, and primer. If ethanol has been allowed to degrade the fuel line or the primer bulb, it could be clogging the valve and causing the problem. Hope this helps!

    You indicated the rubber fuel pump bulb had a one way valve in it. Not So... The entrance and discharge valve have the 2 one way valves in it. One on either side of the bulb. The way they work is the fuel tank side allows the gas to flow only in the direction of the bulb and toward the outboard engine. The other side or discharge side of the bulb prevents gas from going backward into the bulb and in the direction of the fuel tank The clamps you should have used are stainless steel single or double ear clamps which are much better because they don't get caught up on things and have that overhanging tail. Ugly

    Thanks for the comment, joe. Depending on the make of the fuel line, it will either have one or two one-way valves as you mention. One is sufficient as once the fuel is in the bulb and past the one-way valve, there is only one direction for it to move: toward the engine.

    Don't listed to these guys. First off, they should know that the grey lines are crap hose. Secondly, it's amazing that that fuel line hasn't collapsed already by looking at the interior liner after cutting. I mean, shouldn't that be a dead give away to replace the line?! Go to your local auto parts store and buy black fuel line and replace every grey line you see in your boat. Lastly, this wouldn't be an issue if you disconnect your fuel line off your outboard after each use like you are supposed to and run the fuel out of the carb bowls, again, like you are supposed to. Fuel demand valves are crap and very unnecessary if you know what you are doing. And if you don't know what your are doing, well, you don't need a boat. But most importantly, don't listen to these bozos!

    +Ricky Anonsen There are two issues at play here. First, all fuel hose,black, grey, whatever, must meet the EPA standard for permeation rate. “Auto parts” hose, rated as SAE J1527, does this and is fine as long as it is used in outboard installations, and doesn’t run below decks. But the second, and much more critical issue, is whether or not the hose meets the Coast Guard standard (USCG Type A) which is a fire rating, and is the hose you need to use with sterndrives and inboards, where the hose runs in the engine compartment. While that’s not likely to be common with a portable tank, we can’t recommend non-USCG hose without potentially creating an unsafe situation. Yes, the lined hose is a pain to deal with. It’s stiffer and more likely to leak at the joints if you don’t take care with the clamps. Yes, if you see the delamination, it’s probably worth your time to just replace the hose (read the full article here: www.boatus.com/magazine/2015/august/how-to-install-a-fuel-demand-valve). But lined hose also will hold up better when fuel sits around in it for long periods of time, particularly if you get a batch of gas with higher-than-expected amounts of ethanol. Sure, you can leave your motor disconnected, and if you remember to vent the tank just before you connect it, you won’t even get sprayed with gas when you pop it back on. But you can also pop one of these into the line for about $20 and never have to think about it again.

    sorry mate your 100% dead wrong. the grey hose with liner is terrible with any ethanol content. its melts and goes all gooey and collapses. its terrible stuff.. now car/auto fuel lines do meet and exceed the certification for hose on outboard motors.. they grey crap meets nothing of any importance when it comes to proper safety....notice none of you picked up the twit not using the paper towel on the second bit and his ultra sharp piece of shit knife...
