Default Help identifying vacuum components

87 coupe. I always thought the rear plenum vacuum line fed directly to the fuel pressure regulator (FPR), but every once in a while my 87 has to remind me that 87's are a little different in places. My FPR vac line goes forward under the middle of the plenum to a "Y", the forward of the 2 plenum vacuum connections connects to that "Y" and that Y goes forward to a tee feeding 2 components I need help identifying so I know what they are. My last ride ended with stumbling and idle issues. I followed the Y forward under the plenum to a tee feeding the 2 components in the photograph and the line (which is too short) had pulled away from the tee, it is the line in the photo with the tie wrap. What are those 2 components at the front of the engine at the tee ?
1. is the line from the plenum and FPR "Y"
2. ?
3. ?
