FAQ

Q1: How do I know if this metering valve (7123-490E) is compatible with my pump?
A: This valve is specifically designed for Lucas/CAV DPA (Distributor Pump Assembly) rotary injection pumps. To confirm fitment, check the part number on your existing metering valve. It should read 7123-490E or be a known cross-reference. If you are unsure, please provide your pump model number (e.g., DPA 3233Fxxx) to our customer service team for verification.

Q2: What are the common symptoms of a faulty metering valve?
A: A failing metering valve can cause several issues, including: hard starting or no start, erratic idling, black smoke from the exhaust (indicating over-fueling), loss of engine power, and poor fuel economy. If you experience these symptoms and have confirmed your DPA pump is functioning, the metering valve is a likely culprit.

Q3: Is professional installation required for this part?
A: Yes, we strongly recommend installation by a qualified diesel injection technician. Replacing the metering valve involves opening the DPA pump head, which requires specialized knowledge and tools to ensure proper sealing and timing. Incorrect installation can lead to pump damage or poor engine performance. Always clean the surrounding area thoroughly before installation to prevent contamination.
