For Tank Panel Plugs: please make sure you measure both tank panel holes, some XJ panel holes are known to measure 2.25" ( 2-1/4") -
I have both size plugs.
For O2 Ground Strap: confirm that your car is a
1980 to 1985 with the Single Wire O2 Sensor.
Later cars do not need this strap.
Jaguar added a separate ground wire
to later O2 Sensors, I wonder why?
