FAQ

Q1: How do I confirm this plunger will fit my injection pump?
A1: Please check the OE number on your existing plunger. If it matches one of the listed numbers (A159, A85, A74, A204, A134), this part is a direct replacement. For non-matching numbers, measure the plunger diameter and length to compare with your current component.

Q2: What maintenance is required after installing a new plunger?
A2: After installation, we recommend bleeding the fuel system to remove air and performing a bench test of the pump to ensure correct timing and pressure. Always use clean, filtered diesel fuel and replace the fuel filter simultaneously to prevent contamination.

Q3: Can this plunger be used in high-performance or modified engines?
A3: Yes, this plunger is made from high-speed steel and is suitable for standard to moderate performance applications. For extreme high-pressure modifications, please consult with our technical team to confirm the plunger’s specifications match your pump’s output requirements.
