GM Head Question.

Starting to order some parts for the winterization optimization mods.

Does anyone know the ID of the "fresh" water side hoses on the Galley Maid head pump off the top of their head? (haha) ?

Gracias.

Awesome, thank you as always.

It appears that the fittings are 3/4" IPS (Iron Pipe Size), which requires 1" ID hose to go over them. 3/4" IPS has an OD of 1.05".

I'm actually not messing with the pump itself. I am Teeing into the supply line between the sea strainer and the pump, so I can close the through hull, open, drain and clean the strainer, re-assemble and then connect an anti freeze supply hose to the T. Flush for a bit and good to go.
