air intake pipe?

[redrocket90gst]

I have a 1990 gs-turbo fwd. i bought a dejon intake pipe with a return tube. Now on my
stock rubber pipe a couple inches after the Mas, theres 2 little rubber tubes. one runs right to the tube on the valve cover, wich i know can be covered with a breather filter, the other one runs under the battery. problem is that the dejon intake pipe doesnt have the fittings for the 2 little rubber tubes. how do i do a succesfull swap with out messing anything up? how can i bypass these rubber tubes, especially the one that runs under the battery? and what is there purpose?

One is for the valve cover breather, as you already know, and rather than put a breather on it, the preferred method is to run a catch can.

The other is for the charcoal canister which is for emissions purposes. So if you live in a state with strict emissions, I would plan on running with that hose. Otherwise, you can just ditch your emissions system completely.

The one that goes under the battery goes to the charcoal canister. Just get rid of the charcoal canister. There is a tech article on here that says how to do it.

a catch can instead of a breather filter? what is a catch can? and if i get rid of the emissions sytem, will that have any negative affects to its performance? and how do i remove the emissions system?

It won't have any negative affects to performance.If anything the car will run better. And there will be less spots for boost leaks. Just take off all the vacuum lines and only put ones on things you need(fpr,boostgauge,boost controller etc.)

The hose that goes to the intake pipe can go to the pcv valve instead.

Ok got how to do the charcoal canister, just remove it and block off the line. but what about the line that is (to a/c) the middle one is blocked off (to carb)
Remove the (to tank) and (to a/c) lines from the canister. what do i do with the ac line? is my a/c still gonna work? and my dejon intake doesnt have the fittings to run a catch can. do i need to run a catch can? what are the benefits over a breather filter? how would i modify my dejon intake to run a catch can? just drill a hole in my intake and find brass nipple to insert, so i can run a line to a catch can?
