Product Details

Built for fuel tank service, the Carter TLR2 helps secure the fuel pump module or sender assembly at the tank opening. Carter’s fuel systems program focuses on OE fit, form, and function with broad vehicle coverage and problem-solving replacement parts. This part cross-references Dorman - OE Solutions 579-004 for the same application. It is a direct-fit fuel tank lock ring for many Ford F-150, Ford F-250, Ford F-350, Ford Bronco, Ford Explorer, and Mercury Cougar applications that use the specified 4.75-inch outside diameter.

What It Helps Fix

• Loose or damaged fuel tank lock ring retention
• Fuel odor caused by a poor seal at the tank opening
• Improper seating of the fuel pump module or sender assembly
• Corrosion-related service issues on the tank retaining ring
• Fitment problems during fuel tank module replacement on Ford and Mercury vehicles

Installation Notes

Verify the tank opening diameter and module style before installation. Clean the sealing surface thoroughly, inspect the gasket or seal, and confirm the ring seats evenly before final tightening. Use the vehicle’s service procedure for the fuel tank lock ring to avoid damaging the tank flange or module tabs.
