Pull the seat frame and then it'll be easy to pull the tank. Two bolts, one on each tank strap. Plus the wires to the tank sending unit, the fuel line under the cab and disconnecting the filler neck.
While you have it out, I suggest getting it boiled out, which should cost you around $30 at a radiator shop.
