Petrol Gauge

[vatchuthan]

HI guys,

I've got a 1998 R34 GTT and my petrol gauge does not seem to read properly.

If i knock the dash above the speedometer it may move down to the correct position or if i go over a bump it may come down. Even after i fill up a full tank of fuel the needle wont move back the F position unless i knock the dash.

Has anybody else had this problem or know of any way i could fix this. I've taken apart the whole speedometer cluster and checked if the fuel gauge needle is rubbing on anything but that does not seem to be the case.

Cheers!
