FAQ

Q1: How do I confirm this metering valve fits my CAV DPA pump head?

A: Please check the part number stamped on your existing metering valve. It should be 7139-559D. Additionally, verify your pump head rotor model (e.g., DP200). If you are unsure, you can send us a clear photo of your old part for visual cross-referencing.

Q2: What are the common symptoms of a failing metering valve in a DPA pump?

A: A worn or faulty metering valve can cause several issues, including: engine surging or unstable idle, difficulty starting, black smoke from the exhaust, loss of power under load, and poor fuel economy. Replacing the valve often resolves these problems without needing a full pump overhaul.

Q3: Is professional installation required, and what is the typical procedure?

A: We recommend installation by a qualified diesel injection technician. The procedure involves removing the DPA pump head, carefully extracting the old valve, cleaning the bore, and pressing in the new valve to the correct depth and orientation. Improper installation can damage the pump or cause performance issues. Always refer to the manufacturer’s service manual for your specific pump model.
