So I just replaced my air filter on an 87 n/a with a stainless steel cone job - made up a connector to the air flow meter with some plumbing stuff and it works great - thing is, what do I do with the hose from the air pump that went into the old air filter box?

 

Go to a local auto parts store (i.e.. Autozone) and pick up a breather filter. That's where I got mine and it cost me $8. Then just stick it on that hose, cutting hose down optional.
If you can't do that then you can order one from K&N. I don't know what it will cost or anything.

 

if u don't have emissions there u don't need ur air pump . just rip it off. it'll give u a little more hp as well.

 

since you said your running an N/A I would say to leave the airpump on unless you want to wire your 6 ports open or remove them
