wouldnt all new fuel lines be ethanol compatible being pump gas is 10% and new cars can run on E85? but then again ive seen fuel lines on boats i work on warp from the ethanol content in pump gas..these are older line the new stuff doesnt seem to have issues. I do have a picture of what the ethanol from pump gas will do to battery cables. we had a issue with an outbaord with a very very slight drip and was pooling up in the control tube..for all the wires and fuel line. we had to replace everything including the fuel line. this boat was a 1986 if that makes a difference on hose from then to now.
