Engine Compatibility

When This Part Needs Replacement
Replace or service the injection pump if the engine is hard to start, smokes excessively, lacks power, surges, runs unevenly, leaks fuel, has poor throttle response, or fails fuel-system diagnostic testing.
Installation Notes
Installation should be handled by a qualified diesel technician. Keep the fuel system clean, confirm timing, replace required seals, prime and bleed the fuel system, and verify operation after installation. Injection pump calibration and timing are critical.
