Maybe this is what your looking for.. you may already know this but on the valve ..top left-from wp..bottom left-to wp..top right-heater in..bottom right-heater out....on the pump 5/8" supply to heater core 3/4" returns from heater core ..I've read where some people remove the water pump fittings and drill and tap and install hose barbs with npt threads..this way you can use a barb size that's correct for your hose. If you mount it on wheel well you could make a sheetmetal cover to go over it so that only the hoses going in and out would show.
