A couple of ways you could save a few steps and money in the process would be to eliminate the "T" and reducer for the hose barb and drill the PVC where the coupler is joined to the inlet reducer, tap it with a 1/8 MNPT tap and use a 1/8" MNPT X 1/8" hose barb, a wrap or two of teflon tape or just a thin coat of silicone on the threads and it's sealed.
I love the threaded coupler idea, that's rather clever, the ones I'm going to be making use a threaded nipple for the body but I'll have to see if your way can reduce the cost by letting me use straight pipe.
