Detailed Description

The Delphi FA10008 is a fuel tank lock ring used to retain the fuel pump module or related tank-mounted component in place. This part number is commonly searched for Ford F-150 fuel tank lock ring replacement, Ford Ranger fuel pump lock ring service, and Ford Explorer fuel tank retaining ring applications. It also serves many Mercury and Lincoln models from the 1983-1997 model years. This part cross-references Airtex Fuel Pumps LR2001 and Carter TLR2 for the same application.

As a metal standard replacement part, the FA10008 is suited for technicians and DIY repairs where the original retaining ring is corroded, damaged, or no longer holds proper tension. Delphi FA10008 is a practical choice when servicing fuel tank access points on Ford Bronco, Ford E-250 Econoline, and Mercury Cougar applications.

What This Part Helps Solve

• Loose or damaged fuel pump module retention at the tank opening
• Corrosion on the original fuel tank lock ring
• Improper sealing or seating caused by a worn retaining ring
• Fuel system service issues after pump or sender replacement
• Fitment problems on aging Ford, Mercury, and Lincoln fuel tank assemblies

Installation Notes and Tips

Confirm the tank opening diameter before installation; this part uses a 3.75-inch inside diameter. Inspect the mating surfaces and replace any worn seal or gasket separately, since no gasket or seal is included. Follow the instruction sheet and seat the ring evenly to avoid cross-threading or uneven retention during fuel tank service.

Quality Assurance

Delphi draws on OE experience and supplier knowledge built over more than a century of automotive development. The FA10008 is engineered as a standard replacement fuel tank lock ring for service work across supported Ford, Mercury, and Lincoln applications.
