When my VW T25 was started for the first time in 10 years, the amount of crud that came flying out of the heater vents was truly comical, and I was expecting similar here when I reattached the air supply hose today for the first time.
I was surprised to find that aside from this little dusting of foam that nothing much came out. I'm sure it will wait until I'm least expecting it to regurgitate something unpleasant...
