Delphi Fuel Tank Lock Ring

The Delphi fuel tank lock ring (also called a fuel pump lock ring, fuel pump retaining ring, or fuel sending unit lock ring) secures the fuel pump module or sending unit to the fuel tank. It holds the assembly firmly in place and compresses the seal so the tank stays sealed.

Key Features:

• Holds the fuel pump module or sending unit securely in the tank opening
• Keeps the tank seal compressed to help prevent fuel and vapor leaks
• Built to withstand constant exposure to fuel, vibration, and temperature changes
• Backed by Delphi's engineering experience as a long-time original equipment supplier of fuel system components
• Useful when replacing a fuel pump, sending unit, or damaged retaining hardware

A fresh lock ring is a good addition whenever the fuel pump assembly is serviced. It helps the pump module seat properly and keeps the tank sealed. Choose the specific part number that matches your application from the available options.
