rusty bolts

ok, so im in the middle of taking my gastank oown to put in a new fuel pump.... and the housing that holds the bolt to the bracket borke.. so th bolt just spins when i try to loosen it.. what am I to do with all that gas there?? its not like i can cut it off with a dremel.

Try taking a screw driver and pry under the bolt head, this will put tension on the broken nut while you attempt to unscrew it. It may get you far enough to cut it off. you can use a dremel, just take a piece of cardboard and use it as a guard for the sparks that fly around
