Thread: Can anyone recommend a good aftermarket Fuel PSI regulator for me? (2005 GP)

Just doing some research in case I need a new one with the Aeromotive 355 I installed last week. I seem to have trouble starting my car now.

Can I bypass the in tank and run an external?

Also, the regulator is in the fuel filter on 04+ right?

its in the canister, no real filter just a sock.

and no in-line filter

Like Scott said, the regulator is in the canister lol

Well I am 100% set on going to a return system. I have to figure out if the 97-03 canister will fit on/in my tank rather than bypass anything I want to do it right. As of now I am going from a 3.0 to a 3.3 pulley until next spring.

I had 2 big pumps, Walbro 255 and an Aeromotive 355

both made my car run like ****, hard as **** to start and it would lean out at WOT 13.5-14 while the stock pump was 10.5-11.3.

I am bypassing the **** stock regulator and converting to the return style system so I can adjust the pressure.

Also doing a check valve or a manual switch to power on the pump on to resolve the hard starting.
