The Amazon price on those fittings are terribly high. You can get the same fittings (1-1/2") at a farm supply store. They're used for fertilizer spray equipment too. Where I live there is Farm and Fleet and Tractor Supply. What I do is make the adapters with a clear piece of hose in between two fittings so you can see that something is flowing. Not that seeing the waste flowing is pretty, but the lake I go to the most has issues with the pump and sometimes it acts like it's working when it's not.
The two fittings are:
1. 1-1/2" male pipe thread/ 1-1/2" hose barb
2. 1-1/2" hose barb/ 1-1/2" quick connect.
I get the 1-1/2" clear vinyl hose from a local hardware store. It only needs to be long enough to slip over the barbs and leave an inch or two for the view window. Just connect the barbs and use a couple hose clamps.
I think I figured I was spending $10-$12 at the time to make them. It's probably a little more than that now but it's certainly less than $27.50 for one fitting. You can also just use the fitting as pictured on Amazon and it will cost a lot less. If anyone's interested I can snap a picture.
