Hi
I have a 68 camaro ss 396 5 spd.
My car has a new gas tank and new sending unit installed 2 years ago.

The other day after fixing my defroster handle behind my dash my fuel gauage now reads in reverse goes up as fuel is used and when i fill up the gauge goes down towards the empty sign.
My gas gauge is located on my floor counsel in the 4 cluster gauge set.

any hints on where to start ???

Thanks

Ted
