Can you explain? It completes ground so that current can flow from a very restricted source at the gauge to the ground drain in the sensor, right? There's only one wire.
What I'm talking about is when you replace that highly resisted source with a straight-to-battery source, with no resistance. The ground circuit is completed through the send, and a full "whatever the circuit can carry" current path is established.
The resistance could be in the actual sending unit, but it's only 90 ohms, not a ton of resistance so far as I'm aware.
I'm a software guy, not a hardware guy, so type slowly so I can follow!
