Volkswagen Repair: 96 Jetta Trek - Broken door lock vacuum line / tubing, car parts store, vacuum line

Question
I have a 1996 Jetta Trek (MkIII or A3?) with a door lock problem.  The locking mechanism fails to actuate any doors other than the one in which I actually use a key. And, after using the key, I heard the vacuum pump running too long, as well as the tell-tale hissing which revealed a leak under the dash on the d/s.  This all seemed to happen after I had a stereo system installed.  Running speaker wire, they must have inadvertently broke my vacuum tubing connector, right at the wire/air-line harness between the inside lower part of the d/s door and the the chassis where it all feeds through the body into the fuse box area above the pedals.  The tubing connector nipple (or what looks like might have been one) is sheared off, and I have two flush ends, which of course will not seal when I reconnect the harness.  What can I employ to seal this connection without buying parts from a dealer.  I am in a relative hurry to fix this.  Any homebrew or DIY tips?  Thanks in advance for your help!

Hi Ronn;
Get some vacuum tubing from your local car parts store like they use under the hood on engines, and make sure it's just big enough to push that little plastic pipe into, but not so big that it slides right in.  There shouldn't be a need to even glue it or seal it if the fit is tight enough.  Hope this works for you, Ronn.  Good luck.
