[QUOTE="Myfast70, post: 12798206, member: 136812"] I run an Aeromotive Eliminator pump on my twin turbo '93 with MagnaFuel filters on both inlet and outlet. The inlet filter is the larger 125 micron plastic mesh and the outlet is the finer 25 micron stainless mesh. I've yet to have any issues like you mention. I will say though that now when I fill my tank I do use the Jaz fuel funnel with the built in filter to minimize debris getting into the tank. My wife has run a large amount of E85 thru her GN with zero issues. Her setup is a custom twin DW300 pump setup that I built with my own aluminum hat. She's logged a lot more miles than I have on my '93 so far. One thing that I have noticed is a bit of sticky stuff (for lack of a better term) on the very tips of the injectors. I wiped it off of all the injectors and managed to roll it into a tiny ball of "gunk". I rolled it around and it seemed to be oil based. I then put it on the tip of a small screwdriver and put a lighter to it and sure enough when burned it smells just like burning oil. Now I have been told in the past from Rocket Brand fuels and a couple other sources that pump based E85 is made up of 85% ethanol and the rest is whatever junk gas and fluids that the refineries have laying around. They said that sometimes the 15% is cut with trans fluid and other oils which would be why the gunk smells like oil when burned by itself. If you talk to Rocket Brand they tell you that their stuff start with 100% ethanol and then is cut with race gas to make it E85 but it also cost $7+/ gallon too. Looking at your pics of the fuel filter above I would say the twisting damage has been done by removing (unscrewing) the filter from the housing. The filter could potentially implode or crush from extreme pressure (beyond what the pumps may be capable of) but excessive pressure wouldn't be able to get it to twist and distort as pictured. I have read somewhere that some guys actually run a tank of 87 octane thru the car every few tank fulls of E85 just to kinda flush the system out. This will require a second tune and an extremely cautious right foot to keep things out of boost to prevent engine damage from detonation. One thing I have noticed is that the Chevron station that I get my gas from has been very consistent at 85-87% E85 when I test it. Never over, never under. Are you going to brand name stations for your E85? Is it always the same station or always different ones? You could always stick with just one station and see what results are yielded although it may not be feasible to do so for some. The Chevron station I use just so happens to be about 5 miles from my house so it's the only one I ever use. That's just some of my experience with E85 I've had in the 6+ years running it and my .02 [/QUOTE]
