The fuel pump pressure may vary by vehicle. However, on average the fuel pump pressure with the engine running should be between 4-6 psig.
the pump pressure should be from 20 psi to 28psi.
Fuel pump pressure depends on which fuel system the car has. If your car has a carburetor then the fuel pressure should be 9 - 13 psi. If your car is fuel injected then the fuel pressure should be about 45 psi.
fuel pressure should be 44.2 -54.2 psi
55PSI
Depending in the hydrant suction, pump pressure should be about 80-100 psi
you should have 2pumps, a low pressure in the tnk and a high pressure in the line.
Need carmaker
If it has no pressure your problem should be on the pump. The three things I'd recommend you to check are: Packings, Unloader and Valve Kit.
If you are asking what the pressure should be, it should be 5-6 psi but we really need to know what year and engine that Chevy has to correctly answer that.
Most mechanical fuel pressure, if equipped with electric pump, should resd 35-45psi
No. you may want to look for a restriction or a fualty pressure regulator.
