Since this involves removing the bed I want to use a good quality pump. Any Brands recommended or any brands I need to stay away from?

I googled this because we have the same truck. Looks like you can drop the tank also:

Everyone I've talked to said raising the bed is the easier option, but they also told me an AC Delco fuel pump is worth the extra money.last oem part I bought from the dealer failed within a week. Looking for a better less expensive option

It's been a while so I couldn't say about brand, but bed removal is easier than dropping the tank.

I have a goose neck hitch. Following this since I'll probably be doing it soon as well.

Oem.  From the dealer.  It is a painful truth that even an aftermarket Delco pump is not of sufficient quality to RUN THE DAMN TRUCK!

Another painful truth is the OEM from the dealer oil pressure sending unit I put in the 6.0 L crate motor in my Denali failed within a week. Would an AC Delco from the local FLAPS be  the same as an AC Delco from the dealer?

Find the Delco dealer that the dealer buys from. Most of the dealer parts comes from this place not GM themselves.

The FLAPS has been here longer than the dealer has been here, and much longer than any of the other big box auto parts stores that have moved in.

I had a 90's same truck, the metal tubing rotted off because it's on top of the tank, under the bed and never sees daylight but is constantly peppered with everything from the ground.

Depending on how nice your truck is, you may not want to do this.  Locate the pump location, drill two small holes in the bed and then saber saw or whizz wheel a small square of bed flooring out.  Fix the pump. 

To replace the floor, I welded four small tabs of flat stock on two sides.  Place the removed floor pan, drill holes through the pan and the tabs.  Remove the pan material, tap the holes in the tabs.  Done.

You will have a gap around the cove the width of the cutting blade.  This can be filled with weather stripping.

If I can get a good enough fuel pump this should be the last time I have to replace it that's good information though

Bought an AC Delco from the auto parts store, dealer didn't have one for this old a truck. AC Delco was $100 higher but I don't want to do this again right away. Bed doesn't have to come all the way off I raised it up about two feet and used an air chisel to get the retaining ring back on the top of the tank. Truck runs now.

And swap out the fuel filter too. I went through all the gyrations of swapping the pump in my '93 and it turned out to be a bad filter instead.

I can't believe that the Big Three still do this nonsense. All of my Eurocars have had easy pump access.. even my Land Rover has a floor that can be unbolted and removed to get at the top of the tank.
