So I got a round aluminum VW dune buggy side fuel cell on the cheap. got it installed in my CJ and its working out great. Down side is that it does not have any baffles in it. I have been toying with the idea of ordering a block of fuel cell foam and cutting in into cubes big enough to push into the filler neck and fill the cell that way. Is this a good idea? is there a better way of adding some type of baffle?
