Default Sending Unit Wiring

Just need someone to confirm my understanding of the wiring on my new 82sending unit so it doesn't go boom.

CFI, electric fuel pump, and computer were removed by a PO and mechanical fuel pump was installed.

I get no voltage reading from any port on the vehicle wiring harness I'm assuming because the fuel pump relay etc. has been removed, but to be safe I want to remove any hot wires from the new sending unit.
From my understanding, in the photo below:
Purple = Resistor wire from float to fuel gauge for fuel level
Black = Ground to complete circuit for fuel pump
Grey = hot wire for fuel pump
So based on that, I should be able to remove the white wire from the sending unit and me good to go. Let me know if I am spot on or off base. Thanks in advance for all the help.
