Yessir. The suction /discharge line inside the bottle goes all the way to the bottom. There is an elbow with a barbed end for a hose from the radiator, and a moulded in elbow on the lid to vent, to atmospheric, and overflow excess coolant if it overheats.
Thank you on the kudos for the shroud. I am all about having stuff look factory even if its homemade. Now that you got something in place to keep your temps down, you should fiberglass one up yourself as a wintertime project.
