It's not the tank(IT'S THE EXHAUST COMING OFF THE PIECE OF CRAP PIPE WE HAVE TO RUN.
But there are tank problems. I personally saw a few tanks that had slits in the fuel inlet insides the tanks and aleast one that didn't have the brass filter at all.(SO YES THERE ARE TANK PROBLEMS AND ASSOC BETTER RESOLVE THERE PROBLEMS BEFORE MUGEN COMES OUT WITH THERE DRIVE SHAFT CAR.
I'D BE WILLING TO BET THEY LOOK CLOSER AT THERE TOY VERISON AND DO SOMETHING WITH IT.
