Use the following procedure in order to check that the fuel priming pump is operating correctly.
Make a note of the location of the fuel lines from the fuel transfer pump. Remove the two lines from the outlets (1) and (2). Plug the open ends of the tube assemblies. This helps to prevent contaminants from entering the fuel system.
Connect two lengths of 8 mm (0.31 inch) rubber hose to outlets (1) and (2). Place the hoses into a suitable container that is capable of holding more than 3 L (3.17 qt) of fuel.
Energize the fuel transfer pump until a constant flow of fuel is running from the outlet for the supply for the fuel injection pump.Note: The flow from the outlet for the return for the fuel tank will have a slower flow rate.
Measure the combined flow of both outlets with a stopwatch. Fuel flow should be a minimum of 2 L/min (0.53 US gpm).
If there is no flow from the fuel priming pump, strike the pump lightly with a hammer that has a soft face at position (X). This can loosen any deposits that may have formed in the pump. Do not strike the pump more than 3 times. Wait for 10 seconds in order to allow the pump to start.Note: Use of excessive force may damage the pump.
Repeat Step 5 three times. If there is still no flow from the pump, or the flow is insufficient, replace the pump. Refer to Disassembly and Assembly, "Fuel Priming Pump and Fuel Filter Base - Remove and Install".
Reconnect the outlet lines in the correct positions.
Start the engine and check for any leakage of fuel or air from the fuel lines.
