Here is the arrangement for the new settee tank vent, connected into the bow tank filler. I am leak testing the bottom fittings of the re-installed bow tank tonight. So far so good. Next week I am going to fill the bow tank and settee tank to make sure the system responds properly - vents to the sink in the head only. The settee tank fill worked great, overflowed to the bow tank. And no problems supplying from either tank so the air part works correctly.
I sanded off most of the nylon reducer threads (1-1/2" threaded to 1/2" barb) to fit into the 1-1/2" tee. The fit is snug and sealed with DAP silicone aquarium sealer. The retainer is a SS machine screw and a nyloc nut, also sealed with aquarium sealer.
The vented loop is the 1/2" - I ordered it from Defender. Couldn't find one on the shelves around Seattle.
