Does anyone know where to find a 3/4 in garden hose adapter for a active aqua aapw550 water pump?

I need to find a garden hose adapter so that I can connect the female end of my 3/4 in garden hose to my active Aqua water pump does anyone know where I can find an adapter piece like this online? It has to be the RIGHT SIZE! Any help is greatly appreciated.

Here is a link to the model of water pump I'm talking about: https://www.hydrofarm.com/p/AAPW550

I always used to just cut the end off the hose and use the adapter that's included in almost all pumps. Sometimes running them under hot water before you force them on that fitting works best.

I used this and a piece of 1/2 flexible hose to attach to the pump. I used it to pump old solution into my bathtub and fresh solution back to my res.saved a lot of work!

If im understanding what you're trying to do right then just get a 1/2 boiler drain and attach to some 1/2 pvc and connect it to your pump with a 1/2 pvc adaper. You can hook it up and unhook it fast and build for less than $10. All you need is below except a small piece of 1/2 pvc between the two adapters.
