I see the pipe that comes forward and down between the pump and the block it then seem to slit and connect to the pump mounting bracket and some other mounting bracket on the other side.
Does it have special manifolds that the mounting brackets pass the air through to?.

Special aluminum brackets bolted to the front of each cylinder head. A portion of the underside of these brackets were hollow (third pic) and sealed with gaskets when bolted to the front of the heads. Round steel pipes pushed into the upper side of these two brkts. through an O ring. A factory threaded plug would be removed (last pic showing installed plug on a Non-A.I.R. car) to allow clean pumped air into exhaust chamber as shown (red arrows) in the factory illustration below.
This Pontiac design was much cleaner looking than the unsightly exterior metal tubes plugged into the heads that Chevrolet used.
