FAQ

Q1: How do I verify if this plunger fits my fuel injection pump?

Check your existing plunger part number against the OEM numbers listed (3418405005, 3405-005, 3405005, or 103204-51100). This plunger is a standard-size A-type component. If your pump model is an A-type and the dimensions match (25 x 10 x 15 cm package size), it should be compatible. For confirmation, consult your engine service manual or contact our technical support team with your pump model details.

Q2: What is the recommended installation procedure for this plunger?

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 or assembly oil before insertion. Align the plunger correctly with the barrel and avoid forcing it. After installation, prime the fuel system and check for leaks. Always replace the plunger as a matched set with the barrel for optimal performance.

Q3: How can I maximize the lifespan of this plunger in my diesel engine?

Use clean, high-quality diesel fuel with proper filtration to prevent contamination. Maintain regular fuel filter changes and ensure the injection pump is serviced according to the engine manufacturer’s schedule. Avoid running the engine on low fuel, which can introduce air and cause cavitation damage. This plunger is designed for standard operating conditions; extreme wear may occur if fuel quality or system maintenance is neglected.
