FAQ

Q1: Is this plunger a direct fit for my existing injection pump?
A: Yes, this is a direct replacement part designed to meet OEM specifications. Ensure your current plunger carries the number 2418455512 or one of its alternates (2455/512, 2455-512). If you are unsure, please contact us with your pump model for verification.

Q2: What are the signs that my fuel injection plunger needs replacement?
A: Common symptoms include hard starting, rough idling, reduced engine power, increased fuel consumption, and black smoke from the exhaust. These issues often stem from a worn or scored plunger that cannot maintain proper fuel pressure.

Q3: How should I install this plunger?
A: Installation should be performed by a qualified diesel mechanic. The plunger must be cleaned with diesel fuel before installation and lubricated with clean engine oil. Ensure the pump housing is free of debris. Improper installation can damage the plunger or the pump barrel.
