    Those with an intank pump Are you running an additional filter other than the one by the tank? Also what size are the return and feed lines on the carb? Mine should be in next week and I'm trying to get a head start on the fuel lines and fittings.

    For the 600 hp system they recommend 3/8" (-6AN) supply line and at least 5/16" (-5 AN) return line.

    On my son's unit he is using external pump with filter before and after the pump -6 supply and -5 return .

    He is also having a intermittent stalling problem no time as of yet to fix the problem.

    I started my install yesterday. Had a dumb mistake that set me back some time. Had to change my studs out for my manifold, dropped a nut in engine, and I don't have any magnets at home besides a small pocket screwdriver. Ended up dropping the screwdriver in there also. Lol. Went out and got one at advanced auto and got it out, but wasted alot of time.

    Mine is great, night and day difference. I really enjoy driving my car now. It was fun before but it just never ran right with the carb. Its the best money I've spent on my car.

    I was still having a problem with the idle hunting and not snapping to the set rpm when I let off the throttle. Spoke to FiTech tech last Friday and got the IAC set right. I need to adjust the timing curve in my EDIS ignition. I have the EFI set for 850 rpm idle but the ignition tries to advance starting at 800 rpm, I think they are fighting each other. I've revised the curve on my computer, just haven't had a chance to upload to the ignition yet. I'm away on vacation until Sunday.
