40psi +/- 5
9 to 13 LBS. It CAN'T be any LOWER are HIGHER It must be within that area.
9 to 13 LBS. No higher are lower are you will have running and are starting problems.
v8 EFI engines 35 to 45 psi
30psi
Just a short burst at pressure. It is not so much the volume but the pressure I look for. Fuel pumps are the #1 problem on these models.
the pressure should be between 35 and 42 psi in the fuel rail. It has a valve like the one for air in the tires to measure the fuel pressure.... MOA.
The fuel pressure should be between 40 and 70 psi on a 96 Buick Regal with a 3.8. If the fuel pressure is above 70, then it is to high and should be checked out by a trusted mechanic.
The 4.3L engine in 2002 should have 60 to 66 psi of fuel pressure.
45-65psi
