FAQ

Q: How do I confirm this part is compatible with my engine’s fuel pump?
A: The surest method is to cross-reference the part number stamped on your original head rotor. Match it with our listed part numbers (7139-360U, 7180-560U) or OE number (7139360U7180560U). If unsure, consult your engine or pump service manual.

Q: Is this a complete fuel pump assembly or just a component?
A: This listing is specifically for the head rotor assembly within a DPA-type fuel injection pump. It is a critical internal component, not the complete pump housing.

Q: What are the benefits of using a high-speed steel rotor?
A> High-speed steel offers exceptional hardness, heat resistance, and wear characteristics. This translates to a longer service life, consistent fuel pressure over time, and reliable performance in high-RPM, high-pressure diesel injection systems, reducing the frequency of rebuilds.
