It's now time to put gauges on the system to check pressures and to observe sight glass.

BTW, I agree with leathermang. Going to Oklahoma is a scary thought, but scarier for me than for him. I live so close to the Red River that I occasionaly have a nightmare in which the Red River changed course and went south of me making me an Okie. When this happens I wake up drenched in cold sweat.

Have a great day,
