As Bill's hyperlink shows, these are the check valves that
I'm writing about. I was wondering how they disconnect
from the tube going to the exhaust. I can see the clamp on
the upper part, but the lower part looks a little funky.
It looks like a 3/4" hex fitting on a 5/8" tube. What's the
best attack on this end? Also, my parts guy says the
the two check valves are the same part number, does
that sound right?
Bill, thanks for the link.

Re: '89 YJ 4.2 Pulse air?
It really doesn't hurt anything being there, all it does is pump
fresh air into the exhaust, it may cause a back fire if there to much
unburned gas, but it surely isn't responsible for water in your air
filter box. That may have come from water actually being splashed into
your intake tube, or very rarely from the valve cover blowby tube from
short distance runs where the engine never gets to full operating
temperature. Plus you may have to pass SMOG tests again.

Bill, I cut and paste this from your link...

The checkvalves in the Pulse Air System prevent backflow of exhaust
into the carburetor. If one should go bad (stick open) and allow this,
exhaust and water will spit into the air cleaner and be sucked down
the carburetor. This is not good. Note that these tubes enter on the
inside (clean side) of the filter element. This condition will lead to rust
in
the tubes, as seen in this photo, and rusty or sooty stains inside the
air cleaner (this one has been cleaned). DaimlerChrysler is very proud
of its checkvalves, and a new one will set you back about $50.

I have the water, I have the rust, if the shoe fits.........
Thanks for your help.
