914 hose routing question
 

I am getting ready to put the engine and trans back in the car. It is a '73 1.7 with the stock fuel injection system. I have my fuel lines mapped and routed and understand the flow on the engine side. The fuel pump is in and lines labeled. I installed the unit pictured below, (and I know there is another vacuum attachment that goes above it). What I don't know is what the circled unit is called and what the hose coming off it is connected to. Any insight would be appreciated. I know the electrical connector is on the engine harness and I have that part ID'ed.

That is your MPS manifold pressure sensor. It connects to a port on the plenum.
