🔌 Function

Draws diesel fuel from the tank and supplies the injection pump at stable low pressure.

⚠️ Common Signs of Failure

• Hard starting or loss of fuel prime
• Low delivery pressure or flow
• External fuel or oil leakage
• Unstable running under load
• Internal wear, noise or contamination

🛠️ 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
