Re: '89 YJ 4.2 Pulse air?
Good luck trying to take them off!
I would recommend soaking them several times a day for at least a week
in a good penetrating oil.
That rust you see can make the tubes paper thin and the odds are it will
just collapse under torque.

Re: '89 YJ 4.2 Pulse air?
Are you thinking that the water in your air cleaner is coming from the pulse
air system? I don't think the water could be coming from that particular
source because the pulse air system injects cold air into the exhaust
stream, and the intake track is not connected.

I just said the same thing as Bill, the pulse air is not responsible for the
water in the air cleaner. I guess I just learned something new.
Be very careful working with that air tube manifold, it breaks very easily
and costs lots o money. I was not able to find one for under $120, and it
was used. The only new one that I found was about $175.
I eventually removed the air tubes entirely, 4 of 6 were broken, and plugged
the holes with brass plugs from Homey D's.
