This will hopefully be easy for one of you Techy VR Geeks to answer.
Stock 02 AFP intake and injectors. The injectors have two seals, and a "screened and vented" section between the o-rings where they plug into the manifold. The manifold has a hole at 6 o'clock that connects to a chamber that connects all 6 similar injector ports together. On the front of the manifold, there is a plastic 3/16" or so hose barb that connects this chamber to.... something, in the stock configuration.
The application for this engine is a few million light years away from stock, but I have an interest in employing these injectors because of their compact size. Can anyone tell me what this vent/feed system in the intake may be for? Venting fuel vapors out, or back into the intake?
Thanks in advance!
