FAQ

Q1: Is this pump a direct replacement for my Isuzu 4HK1 engine?
A: Yes, this pump (294000-0598 / 22100-E0067) is designed as a direct OEM replacement. It matches the mounting flange, fuel line connections, and electrical harness of the Isuzu 4HK1 common rail system. Always verify your engine serial number and existing pump part number to confirm fitment.

Q2: What are the common symptoms of a failing fuel injection pump on a 4HK1?
A: Typical signs include hard starting, engine misfire, reduced power, black smoke from exhaust, and fuel leaks around the pump housing. If you experience these, check the pump timing and pressure. Our pump is pre-calibrated to restore OEM performance.

Q3: How should I maintain this common rail pump for long life?
A: Use only high-quality diesel fuel with proper filtration (min 30-micron). Replace fuel filters every 500 hours. Avoid running the tank dry, as air in the system can damage the pump. We recommend annual inspection of the pump mounting bolts and fuel line seals.
