The two openings circled in Red are threaded (2in FTP) to connect your 1-1/2in vacuum hose fittings.
The two openings circled in Blue are not threaded (3in tube); one connects to your boom using part #10014357 ( 6in x 3-1/2 compression Coupling) and the other end gets plugged using part #10011333 (Jim cap 3in)
