FAQ

Q: How can I confirm this plunger assembly is the correct part for my Zexel injection pump?
A: The most reliable method is to match the part number stamped on your original component or listed in your engine’s official parts catalog with our primary part number 131150-2620 or its alternative A814. Cross-reference with your pump model number is also recommended.

Q: Is this part sold individually or as part of a kit?
A: This listing is for a single, genuine Zexel plunger assembly. For a complete repair, other components like delivery valves, springs, and seals may be required. We supply a full range of related fuel injection parts—please inquire for kits or related items.

Q: What are the typical symptoms of a failing plunger assembly that this part would fix?
