E85 and preferred fuel lines

A. Don't know what ethanol does to rubber lined hoses
B. Don't believe that ethanol has any affect on rubber lined hoses
C. Have the rubber lined stuff laying around, and don't want to spring for new stuff since the hose ends are not the same for rubber vs. PTFE
I did the lines on my old Camaro rubber lined first...after a couple of years, the fumes got really bad (and that was only E10 standard pump gas), so I had to replace them with PTFE, and that wasn't cheap. It really wasn't cheap since I basically did the same job twice, although PTFE wasn't available when I first did the lines.

As said above Synthetic Rubber Hoses seem to work fine, havent heard any issues with people using them but everyone I know using them does not allow E85 to sit in the fuel system for a prolonged period of time. Natural Rubber lines are degraded by E85 over time and can cause some serious issues. PTFE is the ideal material to use but it is a major pain in the *** and about 30-40% more expensive than Synthetic Lines.
