358-9085 Fuel Injection Pump — Cat 314D 315D

This is a high-pressure fuel injection pump, a critical component of the engine's fuel system responsible for delivering precisely metered fuel to the combustion chambers. Manufactured to meet rigorous OEM performance specifications, it ensures optimal fuel atomization and combustion efficiency, unlike a worn pump that may deliver inconsistent fuel volumes. Operators might observe a loss of engine power, rough idling, or increased exhaust smoke when this pump begins to malfunction.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A noticeable reduction in engine power and performance, especially under load, is often the first indication of a failing fuel injection pump. The engine may also exhibit rough idling, misfires, or difficulty starting. Prolonged operation with a faulty pump can lead to uneven fuel distribution, increased emissions, and potential engine damage.

Installation Tip

Ensure all fuel lines are properly flushed and free of debris before connecting them to the new pump to prevent contamination. Overtightening fuel line fittings can damage the pump's ports.

Service Note

Replace the fuel filter(s) and inspect fuel lines for any signs of damage or blockage when replacing the fuel injection pump.
