Smog system breather is my guess I got the old can type in mine. But the Caly emissions are different than here. I never saw that air intake hose running by battery anywhere but in the sun state
i think i remember reading somewhere that is a sort of muffler for the air pump, so you would not hear the air pump sound, again i do not really know it was a few weeks ago when i read it and thats is how i interpreted it.
I have one of those on mine also .... I just figured it was a filter to keep large chunks of debris out of the AIR Pump. Mine is located in the same place.
That makes sense because when the hose was off there was a loud putting noise coming from the end of the hose, which went away when I disconnected it. Thanks a bunch guys.
It's cool dude. I think those guys might be on target with the "muffler" idea since it quieted down the noise quite a bit when I reattached the hose. Thanks Andy.
