Rain sensitive fuel guage :S

[Tatty Chap]

Any idea why the fuel guage on a 2.0l AC would only work when its been driving in the rain?

Could water be getting on top of the fuel tank and reconnecting a bad connection, or would it possibly be windscreen wipers / Headlights?

I dont have a temp guage so cant use that to diagnose the fault

sounds like the sender connections need to be cleaned and the earth points too
