 I have just bought a 1966 Viva HA90 Deluxe Model. The fuel gauge is a bit iffy 1 minute it's showing full and the next 3/4 empty...Any ideas ?

Hi there, 

A Viva HA, not many of those about. Stick some pictures up on here, and show us your car. 

As regarding fuel gauge, it may be worth seeing if you can remove the sender unit from the tank to see if it's sticking. If that seems ok, then maybe check wiring to the fuel gauge. 

Look forward to seeing pictures, and hope i have been helpful.

Regards Andy.
