Replace my Waste Deck fitting

[Pitman]

Need to replace my Waste pump out Deck fitting on my hunter 31. They no longer sell a pump out adapter that will fit the present fitting. My Question is what size should I use. There seems to be 2 chooses 1-1/2 & 1-1/4. Also what size is the hose that connects to this fitting? Any hints on how to go about this job would be greatly appreciated.

What size is your current fitting?

You may not need to replace it...SeaLand offers an assortment of adapters--1.5 and 1.25, 11 and 16 tpi.If you do have to replace, you want a 1.25 thread by 1.5 barb to fit 1.5 sanitation hose.
