No reading on Fuel

Just replaced my gauges on a 1992 250, everything is working except the fuel gauge. It just blinks at the lowest indicator, however, I have a full tank. I have replaced the connections from the sender unit on the tank to the gauge and still nothing. Before I replaced the gauges they showed no display, but after re wiring the lot and installing new gauges everything is up and responsive except the fuel.

your sender should be hooked to white on gauge and the sender ground hooked to a good ground n your system. it that doesnt work pull sender and move sensor manually , sensor may also be bad.
