    The only real issue I see you running into is your fuel gauge. 98+ gmt400 gas trucks run the fuel sending unit to the pcm, and it in turn runs the fuel gauge. With an 0411 you use an express can fuel system as it used the sane fuel gauge setup, but I don't know if any p59's that use this style fuel gauge setup? If you have hptuners they have the fuel gauge tables mapped out to make it work(several on the fakebook ls swap page have done it), but efilive doesn't have them available, so you would have to find/build .cax files, or run a fuel gauge interface module. I have been contemplating going from my p01 0411 to one of my p59's to play with e85 on my 99 l31.

    YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
    MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
    DUCT TAPE.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

    Well I never got around to doing it. One day perhaps, but there is now a boost OS based on 12216125 so I'd probably go that route first.
