Gas tank change

[fball1208]

I have a Craftsman Incrdi Pull 55cc saw that i got as part of a trade, saw runs great but seems to be leaking fuel out of the tank. Anyone have instructions on how to replace this as it looks like the whole motor assembly needs removed. Or does anyone know where this thing could be leaking fuel from? I wiped the underside dry and nothing came but after sitting for a few minuets there was fuel on the ground.
