E85 and preferred fuel lines does this work effectively? I requested PTFE recently and my installer installed this. Before I throw a fit, will this hold up to E85?

Agreed...it'll work for the time being, but PTFE line should have been used. I think people don't use it because they:
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.

Doesn't it say alcohol compatible...???

The synthetic rubber hoses should be fine for E85, I've been using the same for over 7 years now on my Camaro with no problems what so ever. I use the synthetic rubber AQP which should be similar to that but you would want to talk to the manufacturer directly to be sure. I used the PTFE stuff on my GTO when I did that fuel system and what an amazing pain in the *** is it to work with. It's the regular rubber hose that causes problems with alcohol based fuels.

Here is a list of material that my buddy worked on testing as a project for the US gov;
http://iqlearningsystems.com/ethanol...patibility.pdf
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.
