I have a 1970 Starcraft SS which I am installing a 4 stoke on...... would like to put a fuel tank in it that I can take to gas station and fill up like the big boys.. what is the best way?<br />I won't want to cut into floor as I just installed it (should have done this first), but have room in back where tanks used to go... Should I get one that fits where the tanks went? Is there a way to rig a filler cap, etc? gage?
