FAQ
Q: How do I know if this P170 plunger (134151-9020) is the correct part for my injection pump?
A: You must physically check the part number stamped on your existing plunger or the injection pump housing. This part is specifically for Nissan applications and is identified by the model “P170” and the OEM number 134151-9020. If your pump uses a different model or number (e.g., P110, P850), this part will not fit. Always disassemble and verify before purchasing.
Q: Can I install this injection pump plunger myself, or do I need a professional?
A: Replacing an injection pump plunger is a high-precision task that requires specialized tools, a clean environment, and a deep understanding of diesel fuel injection systems. Incorrect installation can damage the pump or the engine. We strongly recommend that this part is installed by a qualified diesel injection technician. We can provide video technical support to assist your mechanic.
Q: What is the typical lifespan of this plunger, and what causes it to wear out?
A: The lifespan varies greatly depending on fuel quality, operating conditions, and maintenance. Worn plungers are typically caused by contamination in the fuel (dirt, water) or simply high mileage/hours of operation. Symptoms of a worn plunger include hard starting, loss of power, uneven running (misfiring), and excessive black smoke. Replacing a worn plunger as a set (plunger and barrel) is the standard repair procedure to restore pump performance.
