What is the Best Fuel Resistant Fuel line? I ve been buying Tygon on eBay but I think alot of it is Chinese knockoff look like because it hasn't performed like I think it should. I don't buy ethanol free gas, but I am going to start. I dose my less than 10% ethanol gas up with Sea Foam ( to stabilize) and marvel mystery oil and that may cause it to deteriorate too. What is everyone using in the tank hose that seems to hold up best?
