Has anyone installed shut off valves on their coolent lines to their espar heater? I picked up some 3/4" brass valves, but they are pretty bulky. I'm thinking I'll install t fittings off the lines to the heater core (and to the engine) for the espar and then install the valves as close as possible to the t fittings. I'd like to support the valves somehow at least. If anyone has pictures of their setup it would be much appreciated.
