Holley Carb

Guys, I purchased a Holley 390 cfm carbuerator to top off my clifford intake and 4.0 head swap. There is one little nipple on there that I am not sure what to do with. I have provided a pic below with the nipple in question. The instructions say it goes to the air cleaner but just how do I get it there. I would hate to think I have to drill a hole and cobble something on a brand new air cleaner.

Thanks,

Jeff

just put a cap on it unless you need it for an air pump ( assume not w/ all the good modifications you have made).
That being said, some situations/distributors respond better to the FULL vacuum there as opposed to the TIMED vacuum port. MOST use the timed port. (That subject has been discussed to death. Look in the "Search" for details if so inclined).
Use one, cap the other. Should be a black rubber plug in the small parts bag.
Good choice of carb,BTW.
