Thanx John
is that a 1/2" larger Radius or Diameter?
Since it seems to be brand specific it would probably be better if the guy that is building the tank tells me the overall Diameter since he is including the bulkheads with the tank. He said 1.5" bulkhead=2.5" hole , but I am confused by that statement. Is he saying that he needs to drill a 2.5" hole to accomodate for a 1.5" bulkhead, or is he saying that the overall diameter of a 1.5" bulkhead is 2.5"
?
I also posted something in the DIY forum. Just figured I would ask here to see if anyone here could help.
