Delphi / Lucas / CAV 7123-620 Inlet Filter Screen | PACK OF QTY 5

Keep abrasive debris out of your fuel system and protect sensitive internal components with this genuine inlet filter screen for Delphi, Lucas, and CAV DPA-series rotary diesel fuel injection pumps.

Mounted directly at the fuel inlet connection, the 7123-620 screen acts as the final line of defense against tank scale, rust, and particulate matter before fuel reaches the internal transfer pump and metering valve. If you are experiencing fuel starvation, intermittent power loss, or hard starting, a clogged or damaged inlet screen is often the culprit.

Key Features & Benefits

Critical Pump Protection: Catches fine sediment before it can score internal hydraulic head assemblies or jam advance mechanisms.

Direct aftermarket OEM Fit: Engineered to original factory tolerances for a leak-free seat inside the fuel inlet fitting.

Durable Mesh Construction: Chemical- and diesel-resistant mesh designed to handle continuous low-pressure fuel flow without collapsing.

Essential Rebuild Component: A must-replace service item whenever servicing, resealing, or rebuilding any DPA rotary pump.

Specifications & Compatibility

Part Number: 7123-620 (7123620)

Common Applications: Widely used on vintage and modern diesel equipment powered by Perkins, Ford/New Holland, Massey Ferguson, John Deere, Case IH, David Brown, and JCB engines.

Condition: Brand New

When replacing the screen, thoroughly inspect the inlet fitting cavity for trapped debris. Ensure the conical end faces the proper flow direction as specified in your pump’s service manual, and install a fresh copper washer or sealing ring on the inlet connection to avoid introducing air into the low-pressure circuit.
