Thanks for the replys.
I'm sure it's not the fuel shut off valve, since I shut that off with 1.5 squeezes from the Mity Vac. And yes, it's the brown line that connects to the valve.
Rubber lines/connectors look good in engine comp't, so I guess it's time to start isolating all the vacuum circuits with a Mity Vac as Johnhef wrote. A good project to do outside in in the sun. It's been raining here the last few days, so hopefully next weekend will be nice.
Also as I mentioned, the rear pass door lock doesn't always actuate (all the others do) so there's something awry, PO had issues with it.
This is a good resource, if/when vacuum issues arise (Nice write-up by Andrew)
