A: The most reliable method is to cross-reference the part number stamped on your original pump assembly or rotor with the numbers listed in our “OEM Cross-Reference” section. Matching the part number (e.g., 7123-359M) is the best guarantee of fitment.

Q: Is this a complete assembly or just the rotor?
A> This product is the head rotor assembly, which is a key internal component of the DPA pump. It typically includes the rotor itself and may include related internal parts as per the original design. Please refer to the product images for exact configuration.

Q: What precautions should be taken during installation?
A> Installation of fuel injection pump components requires a clean environment and technical expertise. Always use clean, filtered fuel to prime the system after installation. It is highly recommended that installation be performed by a qualified diesel technician to ensure proper calibration and avoid damage to the new component or the pump body.
