ACP Mustang Fuel Sending Unit Retaining Lock Ring - 3 Tab (1979-1997)

Restore your 1979-1997 Mustang's fuel system to proper working order with a direct-replacement fuel sending unit retaining lock ring from All Classic Parts. Over time, the original retaining ring can crack, warp, or lose its clamping force, allowing the sending unit to shift inside the tank and causing erratic fuel gauge readings or a compromised seal.

Secure fitment at the tank opening. This three-tab lock ring installs on top of the fuel sending unit mounting surface and locks the unit firmly within the tank opening, restoring the same retention geometry the factory used across the 1979-1997 Fox and SN95 platforms.

Restores original functionality. Whether the existing ring has cracked from age or chemical exposure, this replacement brings the fuel sending unit assembly back to spec without modification. Proper retention keeps the unit aligned, the seal seated, and the fuel gauge reading accurately.
