If you need to replace the fuel sending unit on a Dodge Ramcharger, you'll find it on top of the tank. You'll see wires going to it. If there is no access panel on the bed of your truck, you could take the bed off, but it would be a lot of work. Instead, it would be much simpler to drive the truck until it's almost out of fuel, then unbolt the straps holding the tank in and drop the tank slowly with a jack. You can also disconnect the filler neck.

If you're going to the trouble of replacing the sending unit, you might as well replace the fuel pump at the same time as they come together. You could also try your local junkyards for a replacement, but the old plastic may not be in good condition.
