FAQ

Q1: How do I confirm that this plunger fits my specific pump?
A: Please check the model number on your existing pump. It should start with 294000- followed by a 4-digit suffix (e.g., 294000-0075). If your pump number is listed in the OEM Cross-Reference section above, this plunger is a direct fit.

Q2: What is the installation procedure for this plunger?
A: Installation should be performed by a qualified diesel technician. Ensure the pump is clean and free of debris. Lubricate the plunger with clean diesel fuel or assembly oil before insertion. Do not force the plunger; it should slide smoothly into the bore. Torque all components to manufacturer specifications.

Q3: What is the typical lifespan of this HP3 plunger?
A: Lifespan depends on fuel quality, operating conditions, and maintenance. With high-quality fuel and regular filter changes, this plunger can last 200,000 to 400,000 km or more. Our 6-month warranty covers premature failure due to manufacturing defects, but not damage from contaminated fuel or improper installation.
