FAQ

Q: Will this A78 plunger fit my Mitsubishi 6D15CT injection pump?
A: Yes, this plunger (Part No. 131151-6220) is the standard OE size (28mm) for the 6D15CT engine. It is a direct fit for the A78 type plunger and barrel assembly. We recommend confirming your pump model to ensure it uses the Ad-type plunger configuration.

Q: What is the typical installation requirement for this high-pressure plunger?
A: Installation requires precision. The plunger and barrel (matching set) must be cleaned with diesel fuel and lubricated before assembly. It is critical to ensure no dirt or debris enters the fuel system. We recommend installation by a qualified diesel technician to avoid damage to the pump housing.

Q: How should I maintain this plunger for long service life?
A: Use high-quality, clean diesel fuel and replace your fuel filters regularly. Contaminated fuel is the primary cause of plunger wear. If the engine shows signs of hard starting or power loss, inspect the plunger and barrel assembly immediately. Our warranty covers manufacturing defects but not damage from contaminated fuel.
