Fuel Sending Unit Voltage?

['52 Buick Kid]

Hey guys, just a quick, hopefully easy question for tonight.

I bench tested my fuel sending unit and it's all over the charts. I mean, way out, as in, in the mega ohm reading. No where near the 0-30 reading. So Im looking at going with the TANKS INC one.

My question stems from checking the connection in the trunk. I was always under the impression that there is no voltage going to the sending unit, since its just acting as a rheostat or variable resistor of sorts. With ignition on, and nothing connected to the socket in the trunk, my gauge reads full (as expected since there is basically infinite resistance), but when connecting the multimeter between the socket and the body/ground, Im getting around 2.7v. Is this correct? Just doesnt add up in my mind is all!

Any reassurance would be awesome. Thanks!

I'm sure someone in this forum will answer your question. Wish I could but can't. It just reminded me of what I thought when reading in another forum about in-tank fuel pumps that were called Hotwire.
