Vacum Leak Help

I figured out I have a vacum leak when my Face heat wouldnt work. Hunted the leak down and it is on the passenger side, going into the side wall. It looks like its where the aluminum turns into the rubber. are there gaskets inbetween there that need to be replaced? I dont know how to upload pictures otherwise I would. Its a 93 4.0 btw any help would be great

I know on my 97 4.0 the vacuum line broke right at the hole going through the firewall. Freakin sweet spot for it to break... As far as I know there are no gaskets in the vacuum system, but you could try slapping a little hose clamp on there.

Just cut the line at the leak and use a slightly wider diameter piece of hose to bridge the gap.
