Output pressure during the first ten seconds of cranking:

Normal pressure ... 42 to 70 kPa (6 to 10 psi)

Minimum pressure ... 31 kPa (4.5 psi)

Refer to Testing And Adjusting, "Fuel System Pressure - Test" in order to test the operation of the fuel transfer pump.

Note: When the fuel transfer pump is installed on the engine, ensure that the camshaft is on minimum lobe lift and that the bolts are evenly tightened. Failure to follow this procedure can cause the loss of maximum engine power and damage to the fuel transfer pump.
