    New member and first post. 1964 Scout 80 4 cyl 152ci. I don’t understand the assembly with the Tee on the intake manifold the bottom has a brass piece with a hose going to the crankcase and the top of tee has hose which goes to the fuel pump. This pulls a vacuum on both. What is the purpose? What is the brass piece on bottom of tee?
    Why pull vacuum on crankcase, I thought you should have positive pressure in crankcase. Please help!
    Thanks much.
