Fuel sending unit replacement

I have a 2000 Bravada. How do I replace the fuel sending unit?
Also have a 2000 Sonoma same thing...:disappoin

on the GMs the sending unit and fuel pump are a one piece assmbly, search this forum and the blazer forum for fuel pump replacement.

Here's how I did my '97...should be the same thing.
