I have it all set up finally, but cannot figure out these two fittings. I realize the one on the left fits under the orange cap. It will screw onto the filter housing no problem. But, what is it for? Those are not threads, but barbs like for a push on hose, maybe 1/2" dia or so (haven't measured it yet). The one on the right appears to be sized for a garden hose (haven't tried, but looks about right), but for the life of me I cannot see any place where it connects. The Bestway instructions for the pump indicate a garden hose can be attached at port D (waste port) which is the size of the orange cap, but certainly not the fitting on the right. Honestly stumped on these. Any help @koffey?
