FAQ

Q: Is this Head Rotor a direct replacement for a Lucas/Delphi DPA pump?
A: Yes, this part (OEM 7123-345T / 7180-559T) is a direct replacement for the original Lucas/Delphi Head Rotor used in DPA type pumps. It is a drop-in component designed to match the original manufacturer’s specifications.

Q: What does the “349T” designation mean for the rotor?
A: The “349T” refers to the specific rotor geometry and internal cam plate design. It is a critical identifier ensuring the correct fuel delivery timing and pressure characteristics for the intended engine application (typically 6/9L engines). Always ensure your pump requires the 349T rotor before ordering.

Q: What maintenance is recommended when replacing the Head Rotor?
A: When replacing the head rotor, it is highly recommended to also replace the pump’s drive shaft seal, O-rings, and fuel filter. The rotor and the pump housing’s internal bore should be cleaned thoroughly with clean diesel fuel. Reassembly requires careful attention to timing marks and torque specifications to ensure proper pump function and engine performance.
