you may call any auto parts store to fine this out but i would say about 40 to 50 psi

Any depended on inner maximum mechanic can do a gas pump rigidity attempt on the gas rail rigidity setting up beside the gas injector nozzles. If the gas rigidity is under 35 psi., you elect a clean Delphi or AC-Delco (oftentimes happening kit) electric gas pump. If the motor has a production unit supercharger the rigidity spec is 40 psi. A GM broker won't guarantee the different kind of gas pump. in case you elect a Bosh electric gas pump Robert the non-mechanic will setting up and guarantee it.
