🔌 Function

The feed pump transfers diesel fuel from the tank at low pressure and supplies it through the fuel filters to the high-pressure injection pump. Maintaining steady feed pressure and volume keeps the injection system fully primed under all engine loads.

⚠️ Common Signs of Failure

• Hard starting or extended cranking caused by loss of fuel priming
• Power loss, surging or misfiring under load from insufficient fuel delivery
• Fuel weeping or staining around the pump body, seals or fittings
• Air drawn into the fuel lines, showing as bubbles in the filter or lines
• Low or unstable feed pressure recorded at the filter or injection pump inlet

🛠️ Service Notes

• Work clean: cap the pipes and plug the ports as soon as they are open, and fit new sealing washers, gaskets or O-rings on every fuel joint you break
• Find out what killed the old pump before fitting a new one — dirty fuel, a collapsed or blocked suction line or a restricted filter will finish the new pump the same way
• Fit the pump the right way round for flow direction, and reassemble any drive lever, cam follower or gasket stack exactly as it came apart
• Prime and bleed the fuel system in the order set out for your engine before cranking, and never run the pump dry
• With the engine running, check every joint for weeping fuel and check the fuel supply pressure against the figure in the workshop manual for your engine
