Delphi CAV Lucas DPA Metering Valve | 7139-559AF | Size A Injection Pump

New Delphi/CAV Lucas metering valve (part number 7139-559AF) for mechanically-governed DPA rotary diesel injection pumps. This is the Size A (standard) metering valve, which regulates the volume of fuel delivered to the pumping element. It is equivalent to base number 7139-559.

Key Features:

• Delphi/CAV Lucas metering valve, part number 7139-559AF
• Size A (standard size) for mechanically-governed DPA pumps
• Regulates fuel volume to the pumping element
• Equivalent to base number 7139-559
• Cross-references to Ford D9NN9G586AA and 9918203

Specifications:

• Base part number: 7139-559AF (Delphi / CAV Lucas)
• Size: A (standard)
• Component type: DPA injection pump metering valve
• Condition: New
• Application: Delphi/CAV Lucas DPA mechanically-governed rotary injection pumps

Compatibility / Fitment:

• Fits mechanically-governed Delphi/CAV Lucas DPA rotary injection pumps that use the 7139-559AF metering valve
• Size A (standard) — the Size B (oversized) valve is a different part; confirm your size before ordering
• DPA metering valves are calibration/size-specific by suffix — 7139-559AF is not interchangeable with other 7139-559 suffixes
• Used across Ford, Perkins, and Massey Ferguson DPA applications — the correct valve depends on your specific pump
• Verify against your full CAV/Delphi pump number before ordering; intended for professional pump service

Conclusion:

The Delphi 7139-559AF is a new Size A (standard) metering valve for mechanically-governed CAV Lucas DPA rotary injection pumps, equivalent to base 7139-559 and cross-referenced to Ford D9NN9G586AA. Because these valves are size- and calibration-specific by suffix, confirm your size and verify against your full pump number before ordering.
