Sorry about your gas tank problems. Unfortunately if your installing those engine kit tanks, note they are paper thin. That metal should be at least three times thicker to pull on it with those studs. I had major concerns about my kit tank as well. So I spent a few weeks designing, fabricating and a couple weeks testing a rear tank harness. I realize its unorthodox, looks complicated but the up side, its safe, there is no metal touching the tank and I've had no problems with leaks. Total cost for the harness less than 3 dollars. With some imagination I'm sure the method could be used to mount a kit tank.
