AIR delete question

Ok so I've removed the air pump inside the front bumper. What I'm wondering now is if I have to remove the intake manifold to delete the piping behind it or can I just cut and plug the piping or is plugging it even necessary?

If you've removed the piping from both sides the piece back there is doing nothing. No need to plug it. You do need to plug the vacuum tube where the pump was tho...

The vacuum tube, as in the tube that connects to the air lid? I've done that, just plugged it at the air lid. Just wasn't sure about any of the other piping coming from the other tube where the pump was. Right now I just have one tube on each side next to each manifold. My plan was to just cut each one close to the firewall to avoid pulling the intake manifold. I'm assuming that would be fine?

People buy a breather filter for it and place it in the hole or cap it off on the lid. That is what we did on the Fbody cars.

The vacuum tube is the small line that comes from below the battery. If it's not plugged, you lose control of you hvac vents and create a manifold vacuum leak.

The only lines I see are the 2 that come from the pump, one to the air lid and the one that goes to the driver side exhaust manifold and then to behind the intake manifold then to the passenger side exhaust manifold

The vac line technically goes to the solenoid/valve.

Stealing this pic from Bill Curlee, I circled the vac connection in red:

My AC vents seem to be working fine though. I can't really say if it's affecting idle or not because I just did a cam swap and am awaiting a tune so it struggles to stay running as it is right now

Fine, exactly what I did, not worth removing the intake manifold at the time (and that was 3-4 years ago).

Perfect, that's what I was hoping for. When I decide to throw a set of heads on I can delete the rest of it when I take off the manifold. Just trying to avoid taking it off just for that. Thanks guys

You should be OK However typically when removing the AIR pump and blocking off the AIR tubes on the exhaust manifolds you will get a DTC code---Which then would require tuning to turn the AIR pump function in your ECM OFF as well as deleting all the AIR codes permanently
