The Bulkhead holes on the back of the tank were a little larger than the One Inch Bulkheads. OD Someone used Silicone on it to fix, which I didn’t want. Went to an Ace Hardware, picked up Two #99 1-1/2” x 1-3/4” x 1/8” “O” Rings. Slipped them over the outer threads. They Take up the gap perfectly. On Amazon they are listed as a #222 “O” Ring. I never understood the “O” Ring Numbering!
