Fuel Pump: Testing and Inspection
Fuel Pump Pressure Test 1.
Disconnect fuel line at pump and connect a suitable pressure gage.
2.
Start engine and check pressure with engine running at slow
idle speed. Fuel pump pressure should be as specified. On vehicles equipped with a vapor return system squeeze off the return hose so that an accurate reading can be obtained.
3.
If fuel pump pressure is below minimum, pump must be replaced.
