Issue:
A potential issue has been identified with the fuel filler cap on 2001-03 MY V8 XJ Series and XK vehicles within the above VIN ranges. It may be
difficult for some individuals to properly seat the fuel filler cap since the operation is very stiff. This is caused by a large lead angle on the fuel filler cap
and can result in a high torque being required to fully seat the fuel filler cap correctly.
Incorrectly installed fuel filler caps can lead to a vapor leak and result in the "check engine" MIL being displayed.
