While I'm in there dropping in a new engine, I figured I would replace the rubber section of fuel line going from the tank to the inlet of the fuel pump. I was wondering if anyone knows of a good source for some that is resistant to the ethanol that we are forced to deal with in today's fuels. Would like to source some locally at one of the chain auto stores if they have it, so perhaps an SAE standard would tell me what to shop for.

Thanks.

Goodyear make a rubber fuel hose with a blue liner in it for ethanol fuels,,dont think its uscg approved tho..may want to check with aeroquip..

Not trying to be a smart ass ,but it seems like you have had plenty of time while doing your motor to investigate this fuel line thing .If it was me I would put on some A-1 rated marine fuel hose and get that darn engine in ...Don't let sourcing alcohol resistant fuel hose slow down that engine going in today ...Don't use auto parts store hose .It's barely "lawnmower rated"...Can't you go back later and install the super whizz bang hose after you research it into the ground...Just asking
BTW I think some of the new A-1 marine hose is alcohol resistant .

i got the gray hose says ethanol resistant right on it

Gray hose is B-1 above deck ....like for outboards ..Not uscg approved for below deck....

MPI makes some of the best fuel line for inboard / I/O boat apps for below the deck. We buy 50 ft roles at a time of this 3/8 and 1/2 inch for most boat apps so I have a lot of experience using it plus highly recommend it.

The above post is correct about outboard fuel line as its non coast guard approved for inboards and I/O's depending on its type and rating. Sierra aftermarket marine brands have grey below the deck fuel line.

just when i thought i was doing the right thing oh well guess i need to buy some fuel line too

Teflon braided stainless.

Braided SS hose is not CG approved for use on a fuel system.
