Spectra LO181 Fuel Tank Lock Ring

The Spectra LO181 fuel tank lock ring is a direct-fit hardware replacement for select Chrysler fuel system service work. It is built to match original equipment performance expectations for secure fuel tank module retention on 2004-2008 Chrysler Pacifica applications.

Key Features

  • Fuel tank lock ring for fuel pump module and sender retention
  • OE-style replacement for Chrysler Pacifica fuel system service
  • Engineered with Spectra Premium manufacturing and quality control standards
  • Cross-references Chrysler 4809695AA and 52100410AA

Detailed Description

Use the Spectra LO181 when servicing the fuel tank opening on a 2004-2008 Chrysler Pacifica. This fuel tank lock ring secures the fuel module assembly to the tank and is intended for applications where the original ring is worn, damaged, or no longer provides proper retention. Spectra Premium applies controlled manufacturing processes and inspection standards so the LO181 meets or exceeds the performance level expected from the original equipment part it replaces. This part cross-references Chrysler 4809695AA and 52100410AA for the same application.

What It Is Used For

  • Replacing a corroded or damaged fuel tank lock ring
  • Restoring secure retention of the fuel pump module
  • Addressing fuel odor concerns caused by a poor tank seal at the module opening
  • Correcting service issues after fuel tank or pump module removal
  • Supporting proper reassembly on Chrysler Pacifica fuel system repairs

Installation Notes and Tips

Verify the tank opening, module flange, and sealing surfaces are clean and undamaged before installation. Confirm the LO181 matches the vehicle application and reference the service procedure for the Chrysler Pacifica fuel tank assembly. Proper alignment during installation helps ensure the lock ring seats evenly and retains the module correctly.

Quality Assurance

Spectra Premium backs the LO181 with manufacturing technology and quality control processes focused on OE-level fit and function for the listed Chrysler Pacifica applications.
