I'm also interested in this. I just installed my complete Fore kit with 405 pumps, which were said to be compatible with E-85 by Fore, but now I am hearing differently from Fore.
Basically this weekend at a tuning session with Kurgan, a cobra with 405 pumps that had been in the car for a year...started losing fuel pressure up top. That night the pumps were pulled and the hat and what not was very corroded and the prefilters were full of black gunk.
There are three possible causes in my opinion.
1. Bad pump gas from a station that didnt prepare the pump to be E85 compatible
2. The pumps are being eaten causing the black gunk
3. the lines...(but im not thinking its the lines, as he is using the Aeroquip AQP, however i did see a similar thread to this one where th actual culprit wasn't exposed and the line was sectioned and seemed to rub black/gray on to a white towel)
I am only running barrel fuel so i am removing the bad gas from the equation...so i will check my pumps, filter, and lines after a few hundred miles and report back.
