"My question(s): is this original equipment?"
"Should I shut this off when not using tractor or the valve on the sediment screen?"
Highly recommended. This is a gravity feed fuel system, if you float needle valve fails in the carb you will flood the carb and possible the engine. Lots of posts on this topic. I can turn that valve by hand on my 641.
