Never mind, you must be talking about the BOV recirculation. I thought we were talking strictly vac lines here, of which there are 3. The one for the BOV should be about an inch or two in diameter. There then are 3 vac line type fittings, the larger of them is about 3/8th or so, and goes to the evap canister under the battery. The next smaller one is probably quarter inch and goes to the valve cover, the smallest should be 3/16ths and goes to the BCS solenoid. If any of these things are not being used be ABSOLUTELY CERTAIN THE FITTING ON THE INTAKE IS CAPPED OFF. Using all caps was meant to emphasize that point, for the reason listed in my last post.
