Hey Rick, Any leak on these tanks is not normal, meaning if something’s leaking it can be fixed. If yours has the metal push rod, and you say you did a full rebuild of the tank which would include a new diaphragm, then the leak could be coming from the hole in the diaphragm where the 2 cupped washers are and the push rod threads pass through. I borrowed the 1st picture here from one of crosbyman’s posts but your info is at the red arrow.
