I bought this inlet from the Bass Pro Shop online. Bass Pro Shop
It's $14 and a good deal. I used a 2" hole saw (they say use 1 7/8") and used the screws provided to install. My 3/4" side wall was to thick to use the nut thingie ??? on the back side. (I don't know what it is called) I put a bead of silicone around it just for added protection from leaks.
I wired it straight to a GFCI receptacle and daisy chained the other receptacles to it.
