When the fuel transfer pump is using diesel fuel, the fuel transfer pump has the following specifications:
- Run the pump at 2940 rpm. The full bypass pressure should be
716 to 786 kPa (104 to 114 psi) . - Run the pump at 840 rpm. The flow at
550 kPa (80 psi) must be3.0 L/min (0.8 US gpm) . - Run the pump at 2940 rpm. The flow at
650 kPa (94 psi) must be4.5 L/min (1.2 US gpm) . - Run the pump at 120 rpm. Keep the inlet open to the atmosphere for 10 seconds. Block the inlet. The pump must maintain the vacuum of
30 kPa (4 psi) minimum in 30 seconds. - Run the pump at 840 rpm. Keep the inlet open to the atmosphere for 10 seconds. Block the inlet. The pump must maintain the vacuum of
45 kPa (6 psi) minimum in 30 seconds. - Run the pump at 120 rpm with a blocked inlet for 30 seconds. The pump inlet must have a suction lift of
60.9 kPa (9 psi) minimum.
When the pump is viewed from the drive end, the rotation of the pump is clockwise.
