FAQ

Q: How do I confirm this M38 plunger fits my Isuzu pump?
A: Verify your pump’s model number (e.g., Isuzu PS7100, PE6, or Zexel) and cross-reference the OEM numbers listed. The M38 designation refers to the plunger diameter and helix type. If you are unsure, please send us a photo of your old part or pump nameplate for confirmation.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel technician. Ensure the pump housing and barrel bore are clean and free of debris. Lubricate the plunger with clean diesel fuel during assembly. Do not force the plunger into the barrel; it should slide freely. After installation, bleed the fuel system and check for leaks before starting the engine.

Q: How can I maximize the service life of this plunger?
A: Use high-quality, clean diesel fuel with proper filtration. Replace fuel filters regularly. Avoid running the engine with contaminated fuel, as abrasive particles cause rapid wear. Ensure the fuel injection pump is properly timed and calibrated after replacement for optimal performance and longevity.
