I'm going to replace the fuel pump and the the swing arm will need to come off. I've never done this so I'm looking for tips people might have.
I have the service manual.

On page 4-34 of the manual it says to use the "fuel pump puller tool". Is this necessary? Is there a work around?
What does VSS stand for?
I see there is a gas tank drain plug. Tips on draining the tank?
Also, how did you keep the bike upright whith the swing arm off?

Anything the manual is not telling me?
Anything else you can think of?
Thank you.

Swingarm does not need to come off. If you disconnect the shock and raise bike by frame it will create enough separation to allow fuel pump removal..

Also no special tool needed only the appropriate 1/4-20 bolt to wiggle the the pump out..

You will note that the frame is mounted to the engine, not the other way around. The normal way of doing this job is to suspend the frame from something overhead.

Ive pulled my fuel pump a few times on my XB. last time I found a hole in the corrugated tubing

you can save your self a big, flammable mess disconnect the fuel rail and just pump out most of the gas directly into a can by cycling the key switch.
then you'll only have a small flammable mess to clean up when the O-rings breach the frame.

you can re-use the O-rings if you let the gasoline evaporate out of them so they shrink back down or if you grease em up and are careful not to pinch them. I gather the slack and then guide it in with a pick/screwdriver.

a lift table with a wheel chock make the job a lot easier on your back : )

I did it, the job is over. This is what I learned:
If you have the stock exhaust, you do have to remove the swing arm. The stock exhaust prevents the swing arm from swinging down out of the way. The clip ring holding the pump in is the biggest burliest clip ring I have ever seen. It belongs on a Caterpillar earth-mover, not some dinky motorcycle. Holy fsck me. When I finally got to it I realized the difficult task, went to our local big-tool-store, and bought the largest clip ring pliers they had. Nope, "Fsck you." Not quite big enough. This is the actual tool specified in the service manual After a lot of effort and sweat I finally got it off with a friend and two screw drivers, one of which I broke.
My bike is an '08 and the pump had slightly corroded sitting in the bore. It was stuck. No way it was coming out by grabbing that bolt with a pair of pliers and pulling and wiggling. I finally got a two foot stick drilled a hole in the middle, and inserted the bolt w/fender washers through the hole, it gave me something that looked like a propeller. I then threaded the bolt back into the bottom of the pump and I pulled with a mighty effort. Jesus christ, it was stuck. All the while the bike is swinging from a ratchet strap looped over an A-frame ladder that straddled the bike. It was hillbily-shade-tree-mechanic time.

I may not have been able to follow everyone's suggestions and hints, but thank you for chiming in and sharing. I do appreciate it.

Lol about that clip ring. I fix palfinger cranes. The clip ring for that pump is bigger then anything on those cranes.

I swapped mine a few months ago. A good pair of snap ring pliers really helps. Also, I just threaded a bolt in and pulled out with pliers, no issues...
