Detailed Description

Dorman 904-7370 is a Water In Fuel (WiF) Sensor designed as a replacement for the original sensor used in diesel fuel systems. Its job is to detect water contamination so the system can alert the driver or control module before water reaches sensitive components such as the diesel injector. The sensor uses a 3-terminal, female pin layout with a male round connector, black connector color, and plastic housing for a straightforward OE-style replacement. This part cross-references Monroe Shocks & Struts (e.g., ABPN122WSK4000, N122-WSK4000) for the same application. For buyers searching diesel water in fuel sensor replacement, Dorman 904-7370, or a water in fuel sensor for diesel fuel injector protection, this part provides a focused service solution.

What It Helps Solve

• Water contamination warnings in diesel fuel systems
• Faulty or inaccurate water-in-fuel sensor readings
• Fuel system service issues caused by a worn sensor
• Injector damage risk from undetected water in diesel fuel
• Replacement needs for diesel fuel filter or separator sensor service

Installation Notes and Tips

Confirm the connector shape, terminal count, voltage, and housing style before installation. This sensor uses a round black connector, 3 terminals, and no wiring harness, so the existing vehicle connector must match the sensor design. Verify the application against the original part number 904-7370 and compare the OE sensor layout on the diesel fuel filter or water separator assembly before replacement. Search terms such as diesel water in fuel sensor replacement for Ford, Chevrolet, or Dodge diesel applications are often used when confirming the correct sensor style, but final selection should follow the vehicle’s original sensor configuration.

Quality Assurance

Dorman manufactures this replacement sensor to match OE function and performance, and the part has undergone extensive testing for durability. The construction uses quality materials intended for dependable service in diesel fuel system environments.
