2nd picture is with the sender removed. There is 6 bolts that hold it in place. The holes that they screw into is a blind hole. If the longer bolts broke through the blind hole. What you can do is use some rtv on the threads of the bolts to seal up the hole. Also wipe off the o-ring. Apply a thin coating of grease on it. The grease will let it slide into position easier. Making a better seal there.
