Replace fuel pump

First off, this truck is the XLT. There are a few things I want to know. First, I got a quite of $40.00 from AZ for the electronic fuel pump without the sender. My gauge works fine so therefor Id like to save the extra $100.00. $40.00 still sounded cheap for the pump. Moving on, whats the easiest way to do this job? I've got about 10 gallons of gas in the tank but I've seen videos of pulling back the truck bed for easy access. When pulling off the bed, should I have just 6 bolts to take out of the bed, disconnect the tail lights, and detach the fuel cap hose and that's all? How about separating the sender from the pump. How does that work? Also, when the new pump is installed, what should I do before cranking it? I would like to know about all of this. Thank y'all.
