sounds like crap on the sender causing resistance changes.... there's a TSB on this somewhere warning against using ethanol blended petrol.. the ethanol apparently reacts with the metal on the sender in earlier models (i.e. before 2001) :naughty:
A couple of treatments with fuel injection cleaner has solved my problem.... irrespective of how full the tank was, the gauge showed only half full .. then would drop to zero in a couple of hundred km.. steer clear of ethanol...!
