i bought a GSR tb off a member on d-series.org, and got around to port-matching my mani to get it to fit, and noticed something missing. the little barb that goes to the charcoal canister i believe is gone. i used an air nozzle and blew into it and it didnt seem to take any air...

is there any way i can replace this? am i fucked without it? i was hoping to install this on my motor, but this has me kind of stumped...

pics to know what im talking about

 

sup, thats a vacuum port. There should be a hose from your black canister that goes there. The black canister is locate right under the fuel filter. You dont need to connect it as it is meant to suck up fumes from your gas tank. Just make sure that you plug that hole on the throttle body if its functional. There is supposed to be a nipple there but some throttle bodies are just blocked off and not drilled all the way.

 

sweet! thanks for the info
