FAQ

Q: How do I confirm this plunger is compatible with my specific fuel injection pump?
A: Compatibility is key. The part number 2418455229 must match the plunger specified for your exact injection pump model (e.g., Bosch, Denso, Delphi pump model). We strongly advise you to reference your pump’s service parts manual or provide us with the pump’s model and serial number for verification before purchase.

Q: What is the difference between a “P-type” plunger and other types?
A: The “P-type” refers to the specific design and geometry of the plunger’s helix (the machined groove that controls fuel delivery). Using the correct type (P-type, K-type, etc.) is critical for the pump’s fuel metering and timing characteristics. This part is specifically engineered as a P-type replacement.

Q: What precautions should be taken during installation?
A: Fuel injection plungers are precision components. Installation must be performed in an impeccably clean environment to prevent contamination. The plunger and its mating barrel are a matched set; they must not be intermixed with old components. Use proper lubrication as specified by the pump manufacturer during assembly. We recommend installation by a qualified diesel technician.
