UPDATES
Today I finally got around to changing my fuel pump and installing in the new stuff. I have seen a few threads floating around asking some basic questions so I decided to just make a how to out of my update.
Keywords: Walbro Fuel Pump Install Gas Tank Removal
anyone who doesnt trust my way, go ahead and do it this way,

First of all in order to get to the pump I had to drop the tank. :::sigh::: but oh well the first thing to do is remove the 4 screws holding in the plastic piece around the fuel filler hole.
After that the main bolts holding the tank in place and the lines connected to it need to be removed as well. It is preferable that you drain the tank before hand most likely by siphoning the gas out w/ a tube but I couldn’t get it all out so I did it w/ the tank half full.
There are two electrical clips that need to be disconnected, those can be reached through a small hole in the hatch, or you can wait till the tank hangs up on them to find them and re-solder the clips, up to you.
There are two bolts up front by the differential that adjust the height of the tank, and 4 bolts near the rear bumper support, those need to be broken loose but not completely removed.
I used the help of my old friends jack and jill to help hold up the weight.
After the tank is down and all that dirt has fallen on your face pull it out of the way and take a look at your fuel filter tucked back inside above the differential, now is a good time to change it. Always do as much preventative maintenance as possible.
The two fuel lines connected are a bit tough to reach but w/ the tank out it’s a breeze. I used a WIX replacement filter but if you want the Toyota one here is the part #
After that is hooked up you can move onto the actual Fuel pump, in this case I’m doing the Walbro 255lph pump.
I am a bit anal about dirt so I washed off my gas tank not only to continue the cleaning process but to avoid letting dirt fall into the tank. There are 3 parts that can be accessed the only one we want to mess w/ is the one w/ the gray clip and two fuel lines coming out.
Once out this is what the stock pump should look like, its huge compared to the Walbro. In order to complete the install the new pump will need the electric clip w/ wires, 2 butt connectors, a rubber hose w/ clamps, strainer, and rubber boot. (maybe some instructions but they didn’t help me much.)
Once hooked up it should all look like this, the instructions say to cut the hose to size but I used the whole length to add some downward pressure on the pump to keep the rubber boot in place. (if you see anything wrong with this speak now or forever hold your peace. I was worried about which wire was negative and which was positive but used my black and red logic.)
Assembly is reverse of install. Hope this helps someone.
