Yes, you can. Removal and installation instructions are below.

REMOVAL/INSTALLATION:
Relieve fuel system pressure.
Disconnect negative battery cable. Raise vehicle and remove fuel tank. Remove sender unit and pump by turning cam lock counterclockwise using special service tool J-36608 or J-24187 (contact local dealer or tool supplier for tool)
Remove fuel pump from sending unit by pulling pump up into attaching hose while pulling outward from the bottom support.
DO NOT damage rubber insulator or strainer.
To install, reverse removal procedure.

Can you replace the sending unit by taking the bed of the truck off instead of droping the tank?

Yes. That is the your decision. Most people just drop the tank, but you can remove the bed as well.
