<VV> Gas Guage

[larry at forman.net]

Thanks!   Mine reads WAY over full and I have not yet started trouble
shooting it.  Sounds like my sender is reading infinity, or maybe an
open sender.   I guess that means I need to drop the tank and replace
the sender, but first I will test the gauge and wiring and connectors.

Before we go to the expense and hard work of replacing the sending unit, is there any way we can isolate the issue?  When the tank is full there is no movement of the gauge.  Sending unit appears to have a good ground.  Thanks.
