Thought id change the fuel filter on my 3.0 s-type today and am glad I did as was the first time it had been done.
Easy enough job to do its located behind the n/s/f wheel arch so the liner had to come off (a mix of two plastic screw clip, some T30 torx screws, 10mm bolts)
No special tools to get the fuel line off just some pliers to squeeze the ends a little and pull.
The amount of dirt and grit in the filter was incredible!
