Hi guys,
i have another problem, appreciate if you can offer me some advice on the following....

fuel gauge reading half full and light is on! (at a guess it has just under qtr tank of fuel in it)

what can cause this?

the instrument cluster works fine service lights, tacho, economy etc.
have checked the nuts on back of cluster they are tight.

next i think i`ll take off the cover under rear seat what should i check there?

Sounds likes somethings gone amiss with the fuel gauge sender mounted in the fuel pump. Undo the four nuts on the top of the fuel pump and lift it out.
