well im not sayin it isnt a good pump but some are better than others!! u mite have gotten the factory replacement (aftermarket) but it still only pushes the same amount of fuel!!! like a raptor or air dog the higher the # the more efficiently it can fuel!! + factory replacements use everything on ur truck my airdogg is runnin a 1/2" fuel line and bypassin the fatory liftpump and filter

 

I think you got cheated somewhere along the line (unless your VP44 is going out), because when I installed Mach 1.6 injectors in my '02 (85 HP), it was at least as much of a kick in the pants as installing the Edge EZ was. Not to mention the fact that you should be able to blow a bit more smoke with 80 HP injectors. I hope you get your issues resolved to your satisfaction...

 

mann that suxx too thats what i was thinkin!!! and there goes say 400$ + install... well u could try larger??!! maybe some fireball 150's or smokems. and they arent hard to install just take time!!! me a a bud have put 3 sets in his 01 24v he keeps goin bigger

 

I know it is using 1/2 line to vp pump

 

humm i wish u could tell us what pump it was soo we could do alittle research

 

Thanx for all the input guys it is really appreciated.

 

All I can tell you it has unlimited mileage warranty

i mean do u have like 60$ where u could go and get a fp guage?? that will tell ya if its just a fuelin problem!?? also im assuming you dont have a check engine light butttt if when they changed ur pump they didnt clear the companion code it could be makin ur truck run sluggish (some codes dont pop up on a check engine light)

 

FASS lift pump
