FAQ

Q: Is this a direct bolt-on replacement for my Isuzu 4HK1 engine?
A: Yes, this kit is designed as a direct replacement for the DENSO HP3 pump assembly on 4HK1 and similar Isuzu engines. However, we always recommend verifying your existing pump’s part number against the OEM numbers (294180-0080/0090/0100) to ensure complete compatibility.

Q: What is the recommended installation procedure for this rotor set?
A: Installation should be performed by a qualified diesel technician. It involves removing the old pump assembly, carefully cleaning the mounting surface, and installing the new rotor set, feed pump, and transfer pump. Precise torque settings and timing alignment are critical. We recommend referring to the official Isuzu service manual for your specific engine model.

Q: What does the 6-month warranty cover?
A: The warranty covers manufacturing defects in materials and workmanship. This includes issues like premature wear, internal component failure, or pressure loss not caused by improper installation, contamination in the fuel system, or external damage. Please contact us with your order number and a description of the issue to initiate a warranty claim.
