Ok everyone.. i recently got a new shell and swapped everything from my 180 to the new car.. but when i went for the first drive i noticed the car running dead lean.. i noticed that my fuel pressure was low so i tried adjusting my aeromotive FPR and got nothing over 30 psi so i went ahead and bought a walbro 255 to replace the 190 GTR pump that i had in there.. But i can only get the walbro to push 42 psi with the regulator maxed out and the pump hardwired to a switch. the regulator was fine in the 180 and i never had any problems with it holding around 50-55 psi of fuel pressure.. anyone have any ideas?

 

clogged fuel filter..?

 

i took the filter in the bay completely out and the pressure didnt change.

 

you check the voltage to the fuel pump?

 

I know it sounds stupid, but do you have the supply and return from the fuel rail backwards?

 

42psi? when i turn my key my walbro primes to 45 and idle its at 50, check the wiring you might have missed something

 

lol no the lines arent backwards.. i checked that too.

 

around 13.3 ill check again though.
