Marine fuel line PSA

[mesquito_creek]

I am going to say “hard fail” on Gates barricade green shield fuel hose. This stuff is maybe 6-8 years old but still? If you have any of this junk in your older boats I would check it.

Who has a clear fuel line recommendation?

The ONLY fuel line that I've found suitable for what passes for fuel these days is this stuff..

$9/foot, but worth every penny. Don't waste a dime on anything else

Your 100 percent right it’s Coast Guard rated and has a Teflon barrier. If you were to have a fire on board that’s one of the things that the insurance adjuster looks at.

Wouldn’t clear PVC hose rated for fuel and lubricants just solve 90 percent of your problems? Hey are we getting fuel? Let me just stare at the fuel line and say yes or no? Is there a leak? Let me stare at the line and look for bubbles. Is the tank full of shit? Let me just stare at all the fuel line and I will let you know… etc etc…

green shield is not USCG. There are a few options for USCG with a proper teflon barrier that can be used with push lock or barbed fittings. Push lock is also required to have a crimp fastener (even though it might not actually NEED it to stay fastened)

I've run into this alot with old cars. Sadly, boating is becoming more distant, but I digress. I'm no chemist, but the ethanol content seems to destroy fuel systems from the inside-out. Float bowls start accumulating crapnfrom the interior of the hoses

Side question

does anyone know what size is common from a imco switch to a 496 Mag fuel cooler?

I have an issue with that piece of hose and I might as well replace it with this, but would like to buy it ahead of time

i still don’t understand why or how uscg doesn’t approve the cloth braided lines, or even the “standard” -an fittings. Seems they are way safer than a push-lock to me. But yes also must have a clamp on push-lock to be legal as per uscg

Probably because they won’t pay for the certification process.

I can sort of understand the uscg rated fuel line… but converting every connection on a 6psi manual fuel pump carburated 1987 350 seems like it would cost more than the boat is worth,

ethanol is not rubber hose friendly

Has anybody used the Trident 319 fuel hose? I am about to buy new fuel hose for my boat and I'm leaning towards using this.

because it depends how and who assembles them. A hose clamp that's relatively snug with USCG approved fuel line is pretty idiot proof compared to a re-usable AN fitting assembled improperly.

If Teague sells it, I'd say it's probably OK to good....but the stuff I referenced in post 2 has a wall thickness about twice or more as thick as any normal fuel line I've ever seen. I've got a chunk of it in my boat now that I recovered from a boat I cut up about 15 years ago....it's still just as flexible and in as good a condition than the new pieces I've added over the years.
