FAQ

1. Is this pump a direct bolt-on for my Isuzu 4HK1 engine?
Yes, this part (294000-0039) is designed as a direct replacement for the 4HK1 engine. However, we recommend verifying your existing pump’s model number and engine serial number to ensure perfect fitment, as there can be minor variations in fuel system configurations.

2. What should I do after installing the remanufactured pump?
After installation, the fuel system must be primed to remove air. We recommend bleeding the injectors and checking for leaks at all connections. For optimal performance, adjust the static injection timing to the engine manufacturer’s specification using a timing light.

3. How should I store the pump if I am not installing it immediately?
Store the pump in a clean, dry environment away from direct sunlight and extreme temperatures. Keep the inlet and outlet ports capped to prevent contamination. Do not rotate the pump shaft manually without proper lubrication, as this can damage the internal plunger.
