Its a pretty straightforward install. All you need is a 5mm allen key, an 8mm socket for the seat bolts, and a phillips screwdriver for the tank shrouds and the new shroud mounts on the IMS tank. You might need a 10mm or 8mm socket to transfer the mounting brackets, I forget which.
Yup, the stock tank has a quick disconnect though it can be a bit of a PITA to get loose.
Don't drop the tank before the fuel line is disconnected, because it'll snap off the hose at the pump. This will require a new pump. Ask me how I know... Don't drop the tank after you've removed the hose either and its free to roll around, because you'll snap off the hose. Others here can tell you about that one.
Gas will come out of the fuel line when you disconnect it, so have some towels ready to soak it up.
Be careful that you don't strip the heads on the 6 allen head's that hold the fuel pump in. Have a backup set just in case, they're cheap and you'll probably need at least one.
Use the big honkin' o-ring instead of the stock gasket.
Torque the fuel pump bolts back down in a star pattern to prevent warping the plate and causing a leak.
You'll likely have to bend out the new shroud mounting tabs a little to get them to slide on smoothly.
