FAQ

Q: What is the fitment requirement for the P170 plunger element (134151-9020)?
A: This plunger barrel assembly is designed for standard-size fuel injection pumps used in diesel engines. It is commonly compatible with Bosch-type inline pumps. Ensure your pump model matches the P170 designation. We recommend measuring the plunger diameter (typically 8-10mm) and checking the pump housing for a secure fit. For specific engine models, consult your vehicle’s service manual or contact us with your pump serial number.

Q: How should I install and maintain this plunger barrel assembly?
A: Installation requires precision to avoid damage. Clean the pump housing thoroughly, lubricate the plunger and barrel with clean diesel fuel before assembly, and torque to manufacturer specifications. Avoid cross-threading. For maintenance, replace fuel filters regularly and use high-quality diesel to minimize wear. After installation, bleed the fuel system to remove air pockets. We recommend professional installation by a qualified diesel mechanic.

Q: What is the expected lifespan of this part under normal operating conditions?
A: With proper installation and regular maintenance, this high-quality plunger barrel assembly typically lasts 6-12 months under standard heavy-duty use, depending on fuel quality and engine load. The 4-month warranty covers manufacturing defects, but actual lifespan can vary. Signs of wear include rough idling, reduced power, or black smoke. Regular inspection of the fuel injection system is advised to maximize longevity.
