I have another mustang im doing a fuel system on and were trying to decide which fuel hose to use. Already bought a small piece of Earls Perform-o-Flex hose and it seems nice. I like it alot, but the box says they dont know the long term effects from some fuels. We may end up running the car on e85, so if we use this hose for the rest of the fuel system I want to make sure it is capable of handling e85. Heres a link....Holley Performance Products 3 ft. PC Hose - Size 10, ID .5625, OD .796875 403010ERL
