DarkDave Posted January 21, 2011 Share Posted January 21, 2011 (edited) I think these are "diaphrams". One of them is blown out. I do not know where the vacuum hoses end up. Came off a 83 DL Wagon. Is it ok for me to by-pass them? Any help would be great. Thanks! Edited January 21, 2011 by DarkDave Link to comment Share on other sites More sharing options...
ShawnW Posted January 21, 2011 Share Posted January 21, 2011 Air suction valve silencers. Heres a start on blocking it off. http://www.ultimatesubaru.org/forum/showthread.php?t=107958&highlight=Quarter Honestly I would just replace the reed valve and leave it factory but if you are going to put a weber on it block it off.
