dkmcgowan Posted July 19, 2015 Share Posted July 19, 2015 The vapor canister that came in my 89 Comanche is: 33002870 It's the two port style. One port went to gas tank and the other port went to the top of the airbox in between the throttle body and the airbox. I cannot seem to find a replacement, anyone have luck? I've seen the newer style on the grand and later cherokees that are still round and would mount in the same place, but they have the vacuum connector on them. Where would I get vacuum and would I want it from intake and on all the time, or from somewhere else? Link to comment Share on other sites More sharing options...
Pete M Posted July 19, 2015 Share Posted July 19, 2015 the line to your airbox is considered your current "vacuum" line. or do you mean the newer boxes have 3 lines? Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted July 19, 2015 Share Posted July 19, 2015 http://comancheclub.com/topic/44750-charcoal-canister-qs/?fromsearch=1 I should have a couple extra used rebuildable. 33002870 ones in my parts pile if yours is trashed . Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted July 19, 2015 Share Posted July 19, 2015 Don't hold your breath as most times when you check they no longer have them . This search shows a couple places that's supposedly still has them . http://www.rearcounter.com/33002870-parts995145.html Link to comment Share on other sites More sharing options...
HOrnbrod Posted July 19, 2015 Share Posted July 19, 2015 From an old post: The old AMC canisters in the 80's (p/n 33002870) had a replaceable filter on the bottom like in your picture. You could also change out the activated charcoal at the same time. Unfortunately they are now obsolete unless you find one at the junkyard. The ones used now, p/n 53030500, are sealed units and not serviceable. When they don't function anymore you replace it, ~ $30-$40 aftermarket. Depending on conditions, they are normally good for ~90K miles. Mine started smelling at about 100K miles and I replaced it. They require an additional vacuum line from the intake manifold. 53030500 33002870 Link to comment Share on other sites More sharing options...
dkmcgowan Posted July 19, 2015 Author Share Posted July 19, 2015 so if you go to the newer style, where do you hook the vacuum too on that top nipple? Just manifold vacuum or something? Mine does not have that right now. Link to comment Share on other sites More sharing options...
