    This Saturday.. 4-16 I am installing my Posi race ported eaton, Dragon TB and Plenum both port matched by Posi, GT Pumps, 60# injectors, MAFia, and will be getting tuned on E85 next week sometime (hopefully) My question is should I change my fuel filter while I'm at it? should I put a new one in for the E85? TIA!!

    I would for added safety. However, the best bet would be an aftermarket filter that is smaller then 100 microns.

    Do they make an aftermarket filter less then 100 microns that will hook up to the stock fuel line (with mods listed, I'm assuming he's still running stock fuel line)

    Not for the stock fuel line. They do make them that go down to 10 micron for aftermarket fuel lines.

    There might be a better "stock" filter out there though.

    Then you need to replace the fuel filter before you even start your car with E-85. The E-85 will blow alot of the crap that is in your filter from the gas into your fuel line. It's highly corrosive and may eat away your stock filter. Either way, replace it and look into upgrading the line and adding a 40 Micron fuel filter down the road for added insurance.

    Im pretty sure 10 micron is smaller than 100 micron. So, I would guess 10 micron is the most restrictive(best filtering) element.

    But In order to run anything other than 100, it takes bigger lines?

    Who makes the highest flowing, E85 compatable, 10 micron fuel filter with -10 ends ????

    so technically you could run E85 in a stock vehicle if you change out the fuel filter?

    I'd assume so? That and of course get it tuned... Look at how many flex fuel vehicles there are.

    You are not gonna need -10 lines for what you are doing (and yes you know me :burnout:)

    You need a stainless steel mesh filter, and its most likely gonna be 25 microns.

    Depends...

    Some stock gas tanks are not compatible with E85. You need to get rid off 100% of all the rubber hoses on the fuel lines as well. Fuel filters need to be made of stainless steel [paper filters won't work]. Then you need to account for using 30% more fuel [bigger injectors...possibly bigger fuel lines].

    Been running E85 for 2.5 years with stock parts and no issues. Stock lines, stock tank, stock filter, stock rails, stock hoses(except PPRV delete). No issues even when the car sat for 3 months with a tank of E85 in it.

    Eeeeekkk!!! :poke:

    That's no good! Ouch. Not a good idea at all.

    Just because you haven't noticed anything bad and the car is still running...doesn't mean that it is 'okay'. Half assing a fuel system is never a good idea on a performance car.

    but what about all these new cars and trucks the say flex fuel on them have done then?

    if they go through all that work from the factory just to be E85 compatible then :cuss:

    so say i just wanted to run E85 in my truck and drive it normally. not spraying nitrous or anything but just fill it up with E85. it would be ok?

    Correct! :thumbsup:

    Actually, E85 is not very harmful at all. :read: Most cars built after 1985 will be just fine.

    Here is a good example of what you would typically find when running E85 VS Gasoline.

    And you won't have any problems either.

    The stock lines and hoses are fine with Ethanol. If they weren't compatible, then there would be mass chaos right now because just about every gas station in America has E10 which is 10% Ethanol.

    They have an Ethanol sensor that changes the A/F based on the percentage of Ethanol in the tank.


    Yes, but it would require a retune due to E85's lower Stoich Point.

    I've had it all apart and no signs of anything being bad. I dont need a monster fuel system up here so no need for all the big parts.

    How is it not a good idea? What makes E85 so corrosive compared to gasoline? How is my fuel system half-assed? My power requirements dont need more fuel system.
