OK, part 2 of my fixing the heater. The PO had the white vacuum line pinned off. My manual shows this as having gone direct to the water valve.

If the white line goes to the water valve, where do the other vacuum lines (advance, airbox etc) get hooked in? I can't seem to find the vacuum diagram in the manual

Thanks as per gents!

 

OK...have been trying to figure this out. Here is the only vac routing I could fine.



My car has CCC and a 2 barrel with a/c.

Where do the lines with the arrows go? I cannot find the air bleed valve unless this is what is attached down by the tranny for this set-up?

My carb is also not orientated as per the schematic. I can only see 2 vac lines for the carb. One is right low on the base at the firewall side - I think this is the CCC airbox connector. The other line off the carb is on the passenger side and I would think is for the thermo switch but this still would leave no connection for the rail which runs along the valve cover towards the firewall/tranny.

I was thinking of connecting the line that was supposed to go to the airbleed vavlve to the rail which goes to tranny. This would free up the water valve as a single line egress.
