I'm not 100% positive but I believe the fitting below may be the one broken in your photo.

Ohh very interesting. Thank you for sending that. I didn't realize that you could get just the fitting. That is the only part that is broken.

Do you happen to have any experience replacing them? The black plastic that it is connected to is quite rigid and I would assume brittle as well. Hot water to soft it maybe?

Thanks again!

I found that connector by looking on parts diagrams of similar model years to see if there are any similar looking hoses. That connector popped up on ebay.

I know those hard plastic lines can be brittle. Can try warming it up to soften it and pull out the broken piece, thread in a screw or bolt and try to pull it out.

Can always buy new vacuum hose and make it. Has to be actual vacuum hose and not fuel hose. All im finding is the flexible type vacuum hose. If you need to make a bend in the hose that keeps the shape can always splice in some elbows.

I havent looked around that long to see what diameter that vacuum line is. For my car I was able to buy a small roll of the really small vacuum line.





Just an example of vacuum hose i'm finding locally.

I was looking around and came across part# 2104303229. It looks similar to the photos i'm seeing if the 2104305929 but not really sure.

ECS appears to be selling it.

Thanks for the help everyone.

That line on ECS is interesting... It seems to me like the only difference may be the boot where it passes through the firewall. It doesn't show well in my pictures, but the boot appears to be smaller on the ECS option you posted. I did order the barb fitting from shmebay, so I will give that a try first, and if that doesn't work it may be worth the $60 bucks or so to give the other PN a try, even if I have to swap the boot.

I'll report back in a week or so when the part arrives. Also doing valve covers, plugs, coils, etc. so it may take me a second to get the part installed as I wouldn't want to risk breaking the new piece trying to get all the PCV breather hoses replaced to inlet snout. Parts shipped today for that from FCP, so I'll try and get everything wrapped up ASAP so I can report back.

Thank you all again!
