FAQ

Q1: How do I confirm this plunger fits my pump?
A: Please check the part number on your existing plunger or your fuel pump housing. If it matches any of our listed numbers (294090-0370, 94090-0860, 294090-0650, 294090-1400), or if your pump assembly is the 294000-1191, this part is the correct replacement.

Q2: What is the typical installation procedure for this plunger?
A: Installation should be performed by a qualified diesel mechanic. The process involves disassembling the HP3 pump head, carefully removing the old plunger and barrel set, and installing the new unit with proper lubrication. It is critical to maintain absolute cleanliness to prevent contamination of the fuel system.

Q3: How can I maximize the lifespan of this plunger?
A: Ensure your fuel system uses clean, high-quality diesel fuel and that your fuel filters are replaced according to the engine manufacturer’s schedule. Contaminated fuel is the primary cause of plunger wear. Also, ensure the pump is correctly timed and the injectors are in good condition to avoid excessive pressure spikes.
