Detailed Description

Spectra LO64 is a fuel tank lock ring used in select Jaguar XJ, XJ6, XJ12, and Vanden Plas applications. It secures the fuel level sender, and on certain Jaguar XJ6 and XJ12 applications it also serves the fuel pump assembly retention point. This part number is a practical choice for restoring proper fuel tank serviceability on classic Jaguar fuel systems, including 1969-1971 Jaguar XJ, 1972-1977 Jaguar XJ6, 1973-1974 Jaguar XJ12, 1975-1979 Jaguar XJ12, 1978-1979 Jaguar XJ6, 1980-1987 Jaguar XJ6, 1981-1992 Jaguar XJ12, and 1986 Jaguar Vanden Plas.

What It Helps Address

  • Loose or damaged fuel sender retaining hardware
  • Fuel tank service issues on Jaguar XJ and XJ6/XJ12 platforms
  • Improper sealing at the sender opening when the lock ring is worn
  • Retention problems during fuel level sender replacement
  • Fuel pump assembly securing concerns on listed Jaguar applications

Installation Notes

Verify the vehicle year, model, and fuel system configuration before installation. Match the lock ring to the sender or pump opening on the specific Jaguar application, and inspect the sealing surface and related components for wear or damage during service. For best results, confirm fitment against the vehicle’s original fuel tank hardware before assembly.

Quality Assurance

Spectra Premium uses engineering, manufacturing technology, and quality control processes intended to deliver fuel tank lock rings that meet or exceed original equipment performance for the applications listed.
