About this part

This Dorman tank replaces a rusted, leaking or damaged rear tank on older Ford full size pickups. It is steel with gray paint, 34.75 inches long, and holds 18 gallons. The package includes the tank, a lock ring and an O-ring for the sending unit. Dorman says it directly replaces the original, is made from rugged materials like the original and has been validated for fit and service life.

Fitment notes

The catalog lists 576-121 for the 1990 Ford F150, the 1992-1996 F150 and the 1992-1996 F250. It is the rear tank, 18 gallon size. Trucks often had dual tanks or different capacities, so check your tank size and location. Confirm in the fitment table above, or send us your VIN.
