Delphi DP200 & Lucas CAV DPA Injection Pump 12V Stop Solenoid | Delphi 7185-900W New
Delphi 7185-900W is a new 12 V fuel shut-off solenoid, also called a stop solenoid, with a single central stud terminal. It fits Delphi DP200 series and Lucas CAV DPA rotary injection pumps. It is energize-to-run: with the key on it holds the fuel open, and when the power drops the engine shuts down. It crosses to Perkins 28480007, John Deere RE54064 and RE22744, Cummins 3904630, Case IH J904630 and Ford E8NN9D278AA, and replaces the older Delphi number 7167-620A.
A bad stop solenoid usually means an engine that cranks but will not start, or one that will not shut off with the key. Check for 12 V at the stud with the key on before you replace it. Delphi makes look-alike solenoids in the same body: 7185-900T is 12 V with twin spade (Lucar) terminals, and 7185-900K (stud) and 7185-900P (twin terminals) are 24 V. Match the voltage and terminal style of your old solenoid. Aftermarket copies are sold under this same number; this listing is the Delphi part.
Confirm Fitment Before You Order
Delphi makes this solenoid body in 12 V and 24 V versions with a stud or twin spade terminals (7185-900W, 7185-900T, 7185-900K, 7185-900P). Check the voltage and the terminal on your old solenoid, or send us the injection pump plate number or the OE part number. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

Fits / Applications
- Delphi DP200 series rotary injection pumps that use a 12 V stud-terminal stop solenoid
- Lucas CAV DPA rotary injection pumps that use a 12 V stud-terminal stop solenoid
- Delphi (Lucas CAV) pumps on Cummins, Case and Case IH, Perkins and John Deere engines, under the OE numbers listed below
- Ford and New Holland tractors with Lucas CAV or Delphi pumps (Ford E8NN9D278AA, Case IH / New Holland 83981012)
Check that the solenoid plunger moves freely, and fit a new O-ring or sealing washer where the pump uses one. Torque the solenoid into the pump body to the engine or pump maker’s figure, then connect the switched 12 V feed to the stud and tighten the nut.
