Baystate Jeepers

I need to bore a new hole in my fuel cell for a different kind of sending unit. Im planning on draing it and filling it with water to bore it with a hole saw. I might also Tig-weld closed the YJ sending unit hole adding an aluminum plate to fill that hole. Any other safety precautions I should take. Thanks FjR68

Good thing OSHA wasnt there that day !
