Detailed Description

Delphi FA10027 fuel tank lock ring is a direct replacement service part for securing the fuel pump module to the fuel tank. Delphi has supplied fuel delivery components to global vehicle manufacturers for decades, and this lock ring reflects that OE-focused approach with steel construction and a corrosion-resistant finish. It is a practical choice for fuel system repairs on vehicles such as Jeep Wrangler, Ram 2500, and Dodge Journey, where a properly seated lock ring is critical to maintaining a secure tank module connection. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Used For Common Fuel Tank Service Issues

  • Replacing a damaged or rusted fuel tank lock ring
  • Restoring secure retention of the fuel pump module
  • Addressing fuel tank service work after pump replacement
  • Correcting fitment issues caused by worn or distorted retaining hardware
  • Supporting repairs on Jeep Wrangler and Ram 1500 fuel system service

Installation Notes and Tips

Verify tank and module dimensions before installation, especially the 124.99 mm inside diameter and 181 mm outside diameter. Inspect the sealing surface and replace the gasket or seal separately if needed, since it is not included. Use proper fuel system service procedures and confirm the lock ring is fully seated before returning the vehicle to service.
