Fuel level voltages
Couldn't find the ohms but found that voltage at empty is .6 volts and full is 7.0 volts. you could probe the wires with your meter and check it this way. Pin 26 at the ECM or find the DK Blu/Wht wire along the run to the tank.
If your sender is out of the truck right now you could apply 12 volts and check the output on the other end.
This is the description of the system.

Several schematics of the engine control , first one shows Fuel level sense signal at the ECM/PCM.
