what is this tube?
 
its a 1990 gtu. this is the tube beneath the intake tube. i was replacing the old hks filter with a new k&n. this tube was connected to the HKS filter, and was almost entirely closed off through the filter, due to design, not it being dirty.

what id this tube? do i have to worry about it? can i close it off? do i have to buy a small breather filter for it? what happens if i close it off? etc, etc

Is that your ACV exhaust hose & silencer?
Must not have an ACV, eh?

It looks like you are referring to the air pump hose?

breather filter

GregSL-SE 07-01-04 05:49 PM

It pumps air to your exhaust intake and opens your aux ports.

GeeHee13B 07-01-04 05:54 PM

closing it off is a bad idea then

I'm about to post on the opening of the aux ports with air pump removed so check that post- but other than that I believe no harm no foul. Greg C.
