FAQ

1. Is this plunger compatible with my Isuzu C190 injection pump?

Yes, this “A Series” plunger (Part No. 131101-7020) is a standard size designed for Isuzu C190 and 3AD1 engines. Always verify your pump’s plunger size code (0.4) and housing type to ensure a proper match.

2. What maintenance is required after installing a new plunger element?

After installation, bleed the fuel system to remove air. Check injection timing and pump calibration per the engine manual. We recommend replacing the plunger and barrel as a matched set for optimal performance.
