Re: Factory hard lines from fuel tank to pump?
E5, E10, & E15 Ethanol blends will eat the old J30R7 hoses and even the pre-1994 or so J30R9 and J30R10(in-tank fuel pump) hoses. The other thing that can get eaten is older fuel pump diaphragms, older accelerator pump cups, and float needle tips in the carb.
I run J30R7 hose for PCV and Evaporative Charcoal Can vapor purge hose. I try to use J30R9 for the vapor collection hose, between the tank and the can, because liquid fuel could possibly end up there.
