There are only 3 bolts that hold the tank up. 2 at the front and one that holds the strap in place. I drain the tank as much as possible (down to about 2 gals). On the ST I was not able to get a siphon hose down the filler neck, so I pulled the hoses off the tank bung and stuck my siphon hose directly in the tank.
Next I removed the 2 18mm (17mm?) bolts from the front of the tank and replaced the bolts with loose fitting tie-wraps. This allows the rear of the tank to be lowered (with the tie-wraps acting like a hinge) once the tank strap bolt is removed. Lower the tank slowly using a floor jack with a piece of wood on top of it.
As the tank is lowered, disconnect the wires and evap hose from the top of the tank.
Once the rear of the tank can be lowered to the ground, vacuum/blow off or hose off the top of the tank to remove dirt that might fall into the tank, remove the small bolts that hold the fuel pump assembly in the tank.
The fuel pump assembly can be removed from the tank without removing the fuel line and slung over the leaf spring to work on it. I always purchase Bosch fuel pumps because they're reliable and come with everything needed to replace the pump (including enough submersible fuel line to replace the pump to regulator and regulator to fuel pipe hoses). I believe Bosch PN 69128 is what I bought for my ST. The only other things I had to purchase was a new strainer sock and fuel filter.
After reinstalling the FP assembly, raise the tank and reconnect everything in reverse order. My time start to finish is about 90 mins and I don't work quickly.
If you go with the Bosch kit you'll find there's a bunch of stuff that it comes with that you will not need (O-rings mostly).
