Fuel gauge problem

[paulw]

Hi I have just bought a 98 Excel with 125,000 kilometres The fuel
gauge seems to wander. I can fill the tank and the gauge will suddenly
fall and climb at random...any ideas? Also I have found that in
heavy rain the trunk fills with water. not sure where the leak is
coming from. :roll:

Usually, fuel gauge issues are caused by poor contact in the fuel sender
assembly.
