FAQ

Q: How do I confirm this A43 plunger is the correct part for my pump?
A: First, verify the OEM number on your old plunger element. It should read “131151-2720” or simply “A43”. This part is specifically designed for the injection pumps on Mitsubishi 6D20 and 6D22 engines. If your engine model matches and the part number is the same, it is the correct component.

Q: Can I install this plunger and barrel set myself?
A: Installation of fuel injection pump elements requires specialized tools and a clean environment. It is highly recommended that this component is installed by a qualified diesel fuel injection technician in a workshop with proper calibration equipment. Incorrect installation can lead to engine damage or poor performance.

Q: What is the expected lifespan of this plunger and barrel set?
A: The lifespan depends heavily on fuel quality, maintenance schedules, and operating conditions. Under normal operating conditions with clean, high-quality diesel fuel and regular filter changes, this high-speed steel component can provide thousands of hours of reliable service. It should be inspected and replaced during a standard injection pump overhaul.
