What are you guys using for fuel line? I used Parker diesel rated fuel line, but i notest that some of it is starting to weather check. I don't know if its from the heat of the engine or what, but I figured I would fix the problem before something happened. Is there some good flex line out there, I would like to stay with pushloc since I am not a great fan of Braided AN line.I had some on before and it chafed and wrecked some stuff.
