FAQ

Q: Will this pump fit my Isuzu 6HK1 engine?

A: While the primary application is the 4HK1 engine, the 294050-0651 number is often associated with the 6HK1 family as well. Please compare the pump mounting flange and drive gear to your original pump. If you have a 6HK1, we recommend verifying the part number physically matches your old unit before purchase.

Q: What is included with the pump? Is it a complete assembly?

A: Yes, this is a complete “Fuel Pump Assy” (assembly). It includes the main pump body and the internal hydraulic head and rotor. It does not typically include the external fuel lines, mounting brackets, or the fuel filter. It is ready for installation as a direct mechanical replacement for the original unit.

Q: Do I need to prime the system after installation?

A: Yes. After installing the remanufactured pump, you must prime the fuel system to remove any air. Use the manual primer pump on the fuel filter housing until you feel resistance and the fuel system is full. Crank the engine in short bursts (10-15 seconds) with the throttle at idle until the engine starts and runs smoothly. Failure to properly prime the system can damage the injection pump.
