I am having trouble figuring out why my fuel gauge/fuel sending unit won't work correctly. I took out my sending unit and placed it in the fuel position but it only reads between a 1/4 tank and 1/2 tank. When I place it in the empty position, it reads empty. Anyone know why this is? I pictures of the gauge in both positions if needing to show. Btw, I have an Aeromotive 1000 tank with AutoMeter gauges.
