Do the gage test first. The 64 has a 0 to 45 ohm gage. There's a possibility that the gage ground could be be the problem.Originally posted by Old Longboarder:
When I first started driving my '64 El Cam, the gauge read full, when full and empty when empty.
As time passed, the gauge started reading 3/4 when full, later 1/2 when full, later 1/4 when full. Now, it reads empty all the time.
I am suspecting that the float has filled up with gas and refuses to float now.
I'm tearing it apart today to check it out.
I'll post my findings later today.
