(E) Install the ferrule to the following dimension from the top of the fuel transfer pump body. ... 5.6 0.5 mm (0.22 0.02 inch)When testing the fuel transfer pump is using diesel fuel, the pump should be within the following specifications:
Run the pump at 1050 rpm. Adjust the flow to 2.5 L/min (0.7 US gpm). The full bypass pressure should be 192 73 kPa (28 11 psi).
Run the pump at 750 rpm. Adjust the flow to a minimum of 2.3 L/min (0.6 US gpm). The minimum pressure should be 135 kPa (20 psi).
Run the pump at 750 rpm. Block the fuel flow at the outlet. The pump pressure should be 230 35 kPa (33 5 psi).
Run the pump at 300 rpm. Adjust the pump pressure to 140 kPa (20 psi). The minimum flow should be 1 L/min (0.3 US gpm).When the pump is viewed from the drive end the rotation of the pump is counterclockwise.
