Product Details

The Dorman 904-020 is a replacement O-ring kit designed to reseal a leaking fuel water separator drain valve. When a fuel separator begins to leak, worn or cracked O-ring seals are often the culprit — and this kit allows you to fix the problem without replacing the entire separator assembly.

Key Features:

  • Direct Replacement: Designed to easily repair a leaking fuel water separator without purchasing a new unit
  • Money-Saving Repair: Reseals the separator drain valve at a fraction of the cost of full separator replacement
  • No Special Tools Required: Straightforward installation suitable for DIY mechanics and professionals alike
  • Original-Spec Materials: O-rings manufactured from original-specification rubber for lasting durability
  • Color: Green rubber construction
  • Includes multiple O-rings in two sizes to fully reseal the drain valve assembly

Specifications:

  • Outside Diameter: 1/2 in. and 9/16 in.
  • Inside Diameter: 1/4 in. and 7/16 in.
  • Thickness: 1/8 in. and 1/16 in.
  • Material: Rubber
  • OEM Cross Reference: F81Z-9A153-AA (Ford Motor Company)
  • Warranty: Limited Lifetime

Also known as a fuel water separator check valve O-ring kit, this Dorman OE Solutions part is engineered to meet original factory specifications for a reliable, leak-free seal.
