just put a breather where the tube went up to the stock air cleaner. Leave the other lines alone.

the hose going from your cover to tbi shoud be your pvc valve. it should pull stright out. on the pass side you should have a hose going from the air cleaner to the back top of that cover, all part of your crankcase vent system. If you dont have any opening in pass side you should deffinitly put a breater in there to get some fresh air in. On mine I have the pvc valve with hose going to tbi from the front top of the driver side cover and a hose coming from my air cleaner assm, going to the top back of the pass side.

I dont know what breathers are good thought.

Wow what a repetive reply

 

ok, so only on the pass side, leave the other hose alone, ok
