I just recently replaced the EGR valve on my car because it was stalling out idling rough and a bunch of other things. Now I have a few vacuum lines coming off of the EGR that were so old and dried out they broke. So I'm looking for a diagram to replace them and or can I use a different vacuum hose like a fuel line but smaller? It's also rattling but I'm guessing that's due to the vacuum lines being broken. Correct?

Looks like the EGR only has one vacuum line. If you have multiple lines then I suspect someone may have tapped into the vacuum source.

If this doesn't making sense then I would suggest taking few pictures so we can take a look at them.
