What should fuel pressure be at idle?
When an engine is idling, there is a vacuum in the intake manifold. … With a return system, the base pressure is set with the engine off, but the pump running. For a GM, this pressure is usually set to 58psi (factory fuel pressure in the rail).
How much pressure should a fuel pump have?
On modern automobiles, the average fuel pump pressure is over 60 PSI (pounds per square inch). On classic cars with mechanical style fuel pumps, however, the pressure is much lower—between four and six PSI. If you suspect that your fuel pump is not producing enough pressure, there are two tests you can perform.
