Replacing fuel lines

Postby Huffduf41 » Wed Sep 11, 2019 9:52 am

Hey guys I have some old nasty fuel lines that I'm going to replace before they burn me. I have rubber lines held to barbs w/ hose clamps right now and I'm good with that setup. What material (and who sells it) should I buy?

Thanks

USCG type A1. It is fire resistant and ethanol rated. If run in enclosed spaces it is supposed to be A1-15 which adds low permeability. Any marine store will carry it and unless it’s old stock it will be -15.

Here is some good info:

I grew up thinking I-10 was the Mason Dixon line.

What fuel do you run? Avgas eat ethanol fuel lines up. Now I don't run ethanol in my boats at all so auto store fuel line is the best.

Ted,
I'm interested to know if you have details on the fuel line you had an issue with? I run 100LL with Type A1 fuel hose with no issues. As far as I know all the stuff the auto parts stores sell these days is ethanol compatible as standard since that's the fuel used in autos. Type A1 is made of NBR / Buna-N which is a synthetic rubber used for all types of fuels, same as the auto parts hoses. Just checked Aircraft Spruce and the stuff they sell is NBR too. A1 just has a heavier jacket, larger OD that I find it more durable. It's more costly, but an airboat is still a boat, subject to USGC regs, for what it's worth.

There is s saying in my world "everything for a purpose!"

Reason I don't run that hose is in the past I have seen the inner liner separate from the hose and collapse. Hose looks good but the inner will be unable to pass fuel.

Just my reasons as to selection

Maybe they got better with it but the grey hose was the worst.

X2 with John. Aeroquip is the only hose I will use.
