I am rebuilding a 1986 Comanche. The fuel gauge on reads just below 1/2 tank when full. and correctly shows empty when empty. I had the sending unit out and rebuilt. I have tested the Ohms up to the connector on the firewall and read 93 ohms when the float is in the full position (up) and 3 Ohms in the empty position. I have tested the gauge as well per a previous post and it seemed to be working correctly. Any suggestions on where to look further?
