Item Qty Part Specification Description
- - - 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 be 3.0 L/min (0.8 US gpm).
Run the pump at 2940 rpm. The flow at 650 kPa (94 psi) must be 4.5 L/min (1.19 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 (4.5 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 (6.5 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.
