+1, or your connection is loose (typical bouncing result) or the wire is almost broken (usually in the Engine Bay).

With the power on (not running), if you unplug the wire on top of the sender, you are opening the circuit and it will deflect all the way up. If you ground it (touch the engine) it will go all the way down.

Since the swap is not a direct one, I would investigate the connector/wiring/sender first.
