You said you are visual........the guy at Lowes told me this (see pic) was the best piece to hold the PVC between the inside and outside of the tub or whatever container is used. But they were out of stock and I did not want to drive to another store, so I made a version of my own with pieces that screwed together and bought o rings to fit. It was like a big puzzle to put it all together. I just used sprinkler fittings and 2 RV plumbing fittings (the brass pieces, with plumbers tape) to make it all work. It is a simple y with right angles at the bends. I drilled holes in my PVC with a drill. For the exit pipe, I had some old gray sprinkler riser pipe I thought would be more discrete that white. I used a circular drill bit to drill the 2 needed holes in the tub and sealed with silicone caulk type material. I think the weak point is the thin tub material itself. I suspect it will crack or break where the tube from the pump goes in since there is some pressure on the side there.
The curved piece shows how I made the pipe curve. I used straight pipe cut to the right sizes, one T, and 4 of these C shapes. One at the outer edge and one to have a piece of pipe sticking up. My bog is so tiny I probably did not need the cleanouts. But I have the option if needed. I used screw tops at the piece above the bog and the brass fitting. All of the other joints I used PVC cement, the 2 part stuff that is purple and toxic.
I ended up covering the brass and PVC on the front with black tape so it is more hidden, and not exposed to sun.
