Fan shroud questions.

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.
I have plenty to do and re-do. I am happy with my metal shroud and it works really well. Had I seen your thread first though----
Right now I am lazer-focused on restoring my grille. It will not be stock looking when I finish with it. It is time to install the front end and the grille is first up-----
