I was gonna say, move the APO over and you have a winner.
The 2" dump would have to remain (actually HM uses 1.5" dump on tank.. :roll: ) but you could still make use of 2" hose with a plastic step up at the base of the tank, so it would look like 2.5" 2" and 1" on the face plate. Oh and use 2.5" tubing not 2.5" pipe like you see in the pic, it's thinner but It makes a difference.
