    i used walbro went through 2 of em ,junk in my book .i had to do the work ya know .i wanted accesability.ive got a 1500 dollar pump setup im not going backwards.if you drop a few tanks it pisses ya off.dont mean to sound like a jerk i appreciate the help.it does surge though .maybe i collapsed a filter or it is dirty .ok keep em coming.

    The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......

    aero 11104 pt# im using 2 100 micron filters.cant imagine them beeing that dirty already,but i guess its poss right.seems like thats what everyone thinks,itll hit and miss under accellaration.like a bad plug or wire.thinking of taking off the speed pump controller.
