19. XJS Rear Window Leaks, leading to a trashed fuel tank
Jaguar Parts Technical Information
The rear window on the XJS coupe has a tendency to leak water imperceptibly.
The rear glass seal is to blame. Underneath the fuel tank is a rubber foam
mat. When the water leaks in, it drains down past the fuel tank and
collects in the rubber mat, then starts to rust the bottom of the fuel
tank. This leads to many pinhole fuel leaks. A new fuel tank
is over $500 (plus installation labor) so it pays to ensure that your
rear glass seal doesn't leak
