I live in Tucson AZ. we need to go through emissions. my problem is that there is a plastic tee fitting down near the air pump which has ~3/4" though and a ~1/8" barb off the side. this barb is broken. it has a diaphram inside at the bottom of the small barb fitting. some type of check valve. it use to be sold as part of #12559197 Hose Assembly. This is now obsolete. It is only used on the 99. I am hoping that any of you that have removed your air system might have this part that I could buy. I need to get through emissions before the end of October. I have added a picture of what it looks like.
