    Im about to pull the trigger on e85, but I want to make sure my fuel system, (pumps regulators etc) are up to the task.
    what size pulley is a stock pump good for on e85?
    any parts of the fuel system that will probably fail ( I know I have to replace the filter)

    What injectors should I get?
    I know 42# can be stuck in and run without a tune but its a little rough.
    60# seems where im leaning, but if I have to tune I want to make sure I have plenty of overhead, say if I run an xpz cam, 2.8 pulley etc

    I have headers and an open cone now. Im thinking I could go 3.0"?

    I ran a 2.8 on E85 on a stock pump. You will want to replace your filter after 100 miles and after 1000 miles, give or take.
    60#, 80#, 105# depending on your power goals, if you are staying M90 go with 60#.

    I ran a 3.2 on Headers and E85, 2.8 on Headers, E85, XP Cam, Intercooler
