FAQ

Q: How do I confirm fitment of the P388 plunger for my engine?
A: Verify your pump’s model number and OEM reference (e.g., 134154-0720). The P388 is a standard P-type plunger commonly used in automotive diesel injection systems. If unsure, provide your pump’s serial number or a photo of the old part for cross-checking.

Q: What maintenance is recommended after installing this plunger?
A: After installation, ensure the fuel system is free of contaminants. Prime the pump and check for leaks. We recommend testing the injection timing and pressure after replacement to ensure optimal performance. Regular fuel filter changes will extend the life of the plunger.

Q: Can this plunger be used in high-pressure common rail systems?
A: No, this P-type plunger is designed for traditional inline or distributor-type fuel injection pumps, not common rail systems. It is intended for applications requiring standard injection pressures. Confirm your pump type before ordering.
