FAQ

Q1: How do I verify if this plunger and barrel assembly fits my fuel pump?
A: Check the part number stamped on your existing plunger assembly. This unit replaces OEM numbers 131153-8920 and A768. If your pump uses these numbers, it is a direct fit. For cross-referencing, consult your pump’s service manual or contact our technical support with your pump model number.

Q2: What is the recommended installation procedure for this component?
A: Installation should be performed by a qualified diesel technician. Ensure the fuel injection pump is clean and free of debris. Lubricate the plunger with clean diesel fuel before insertion. Do not force the assembly into the pump barrel. After installation, prime the system and check for leaks. Incorrect installation can cause injection timing issues or pump damage.

Q3: How should I store unused plunger and barrel assemblies?
A: Store in a clean, dry environment at room temperature. Keep the components in their original packaging to prevent contamination from dust or moisture. Avoid exposure to extreme temperatures or corrosive chemicals. Ensure the plunger is lightly oiled if stored for extended periods to prevent rust.
