It looks like the stock fuel pump in my GTP is failing when do a pressure check it reads 25psi on prime and only about 32psi while running. It also loses it's prime in about 2 min if you don't try to start it right away.
I was wondering should I just go with a stock pump or upgrade
My mods are 3.25 pulley full 3" exhaust, CAI, 103 plugs, 3800performance ECU stage 1, and fuel pump rewire.
Thanks guys

you checked the fuel pressure regulator right.
i hope you have headers aswell.
09-28-2011
yeah I checked to regulator for leaking and saw nothing from the spout or anywhere around it. I even disconnected to return line and noticed it was bone dry as though gas had not returned to the tank in ages Which leads me to believe I'm never hitting the correct amount of psi

Do your rpms act weird at idle? Sort of how mines does.

Stay stock you don't have any mods that are going to require you run a stronger pump. Save your money...go stock and buy headers!

If he already has a 3.25 pulley chances are he'll eventually pulley down again.Originally Posted by REDCOMPG
I run a Racetronix and have enjoyed it. It's quiet as well.

Having had a Bonneville where none of the usuals would work, I found TREPerformance.com
$80 is a damn fine price for a 255lph

Thanks for the info guys I'm probably not going to do much more modifying at this point so it looks like the stock pump will be fine. I am wondering what is the reason everyone is saying get headers?? is it due to better flow and the ability to produce more boost?

Headers provide more flow which is always better. When you increase the incoming air it needs a faster way out.
09-29-2011
headers will actually decrease boost for your current setup. but this is a good thing. you will be getting more air flow.... so air wont be backing up showing as boost. this decreases temps for the air coming out of the blower
being able to flow more air allows you to raise the boost more or run more timing. all great things.

take the 3.25 off befor your motor goes boom, right now you dont have enough flow to run that pulley.
Headers will allow you to run smaller pulleys, because as said before you can get the air out faster.

Did you scan his car? Cause then you would know for sure.

Has anyone used Global Automotive products. I found this complete assembly really cheap and I was wondering if anyone else used this and if it's any good
