i got a Gas smell in my cruiser with the hard top on.. Just recently rebuilt the carberator and got it running better.. I think it may have somthing to do with this tube "to engine" writen on it coming out of the gastank.. (picture attached), my engine is a SBC and it has no emissions stuff.. what should i do with this line, and others that may be coming from down there? anything elce that could be causing the gas smell..
