Ok I do see your Ram Charger vac lines within the red circle but don't see where the Strato Vent vac line exits the firewall in the photo. Is it visible or far below the heater? I can see the water valve ok and I can see the vac line where it is connected to the valve but it goes up toward the vacuum reservoir and then disappears. This is helpful. 71 Muffin, your pic didn't show through so I can't see your grommet but have a look at mine way above and tell me if it is identical or near the same.
