Have you confirmed pump/sender failure? It could be as simple as the ground wire to frame with a bad connection.
IMO, if you need to replace, go with the best available parts. Not something you want to do again in a couple months.

i have not. that is the next step i suppose. Do you know where that ground is? is it accessible without dropping the tank or lifting the bed?

If you look in at frame from drivers side rear wheel. On top of frame is a black wire grounded to frame. Clean up that connection REAL good. That ground can be seen in this photo. The connection(circled) that you see is also where you can test your fuel pump.

And to provide supporting FSM documentation for @Caman96's descriptive photo, the Factory Service Manual
refers to this specific ground as G404. And here's the implementation drawing:

The better this ground is, the less guessing about why the fuel system is underperforming. Make it so! :0)
