J have a 1962 Chevy Impala 409 and the fuel Gage worked last year the stoped, I cleaned the ground then worked again. When I took the car out of storage this year the guage was stuck on full and at one point seemed to start working for about an hour, then back to stuck on full. I redid the ground grinding the frame to bare metal and no change. Put in a new sending unit today and the guage is stuck above full???? I am frustrated. Any suggestions
Thanks
Tom
