Michigan | I don't have the electrical schematic but you could run a jumper wire from the sending units directly to the dash. This would help you eliminate a wiring problem as the cause.
I feel your pain, I've got a boxcar with a fuel gauge that is working but for some reason the lower tank sender must have an issue. The dash gauge never reads less than two bars. Even when you are completely empty. Ask me how I determined that! For now the fix has been a sticky note on the dash that says "two bars = empty". | |
