Where is the fuel filter on a 1993 xjs 4.0 cabrio?

Think its underneath by the fuel tank ,but you shouldnt need to change it i have a 94 XJ6 4lt and i have never had to touch anything ,just changed the oil and filter ,evan the plugs havent needed changing in 2 yrs ,but you must polish it every week and clean the leather once a month with that stuff that keeps it supple .and dont forget to polish the chrome exhaust cover on the exhaust manifold
