Spectra LO179 Fuel Tank Lock Ring

The Spectra LO179 fuel tank lock ring is a direct replacement for select Ford, Lincoln, and Super Duty fuel tank applications. It is built to match original equipment fit and function for secure fuel pump module retention.

Key Features

  • Fuel tank lock ring for OE-style replacement use
  • Engineered to meet or exceed original equipment performance targets
  • Manufactured with controlled quality processes for consistent fit
  • Compatible with select Ford F-250 Super Duty, F-350 Super Duty, Expedition, Excursion, and Lincoln Navigator applications
  • Part number LO179 for easy identification

Application Details

Compatible with 1997-2002 Ford Expedition, 1998-2002 Lincoln Navigator, 2000-2005 Ford Excursion, 1999-2007 Ford F-250 Super Duty with midship tank, 1999-2007 Ford F-350 Super Duty with midship tank, and 2008-2010 Ford F-250 Super Duty and F-350 Super Duty. This Spectra LO179 lock ring is used in fuel tank service where the pump module or sender assembly must be secured to the tank opening.

This part cross-references Ford OE numbers such as F75Z9A307AB and F81Z9417AA for the same application.

What It Helps Address

  • Loose or damaged fuel pump module retaining ring
  • Fuel tank service after pump or sender replacement
  • Improper sealing at the tank opening caused by a worn lock ring
  • Fitment issues when replacing an OE-style fuel tank retaining ring

Installation Notes

Verify tank style and application before installation, especially on 1999-2007 Ford F-250 Super Duty and F-350 Super Duty models with midship tank notes. Clean the tank flange and inspect the sealing surface before securing the module. Confirm the ring seats evenly and follows the vehicle service procedure for the fuel system.

Quality Assurance

Spectra Premium states that its engineering, manufacturing technology, and quality control processes are used to produce fuel tank lock rings that meet or exceed the performance of the original equipment they replace.
