Thanks for the info. That's kinda what I thought the symptoms should be.
However, the car idles very smoothly and has no stalling problems when
hot or cold. It even runs smoothly cold with no hesitiation or
stumbling. I suspect that there might be something else wrong if I am
running ok with the bad hose - touched it last night and it just
crumbled and I could feel a hole at least 1" in diameter.

Mike - the primary symptom is a cruddy idle, probably with lots of
stalling, especially when hot. Retail for the big hose on my 200 is
$48, but you can get it for much less. Don't forget to replace the
multi-port hose on top of the rocker arm, too, as it also turns to
much and cracks. Replacing them is just a few minutes' work with a
screwdriver, but do it when the engine is cold....they're right
behind the fan.
