FAQ

Q1: How do I confirm this plunger is compatible with my injection pump?
A1: Compatibility is key. You must identify the part number stamped on your original plunger or the model of your injection pump. Match it to our listed part numbers (PT68 or PT78) or the OE number (1466100312). If unsure, provide clear photos of your old part for our technical team to verify.

Q2: What is the installation process for this plunger?
A2: Installing a fuel injection pump plunger requires specialized knowledge and tools. It involves disassembling the injection pump in a clean environment, replacing the worn plunger and barrel as a matched set (recommended), and recalibrating the pump for proper fuel delivery. This task should be performed by a qualified diesel technician.

Q3: Do you provide technical support or documentation for this part?
A3: Yes. While detailed service manuals are model-specific, we can provide general dimensional drawings and material specifications for the PT68/PT78 plunger upon request. For complex fitment questions, our engineering team is available to assist B2B clients.
