Vacuum hose routings on a b2 80

[billy_bunter]

Trying to sort out what goes where between the air filter, brake servo and vacuum resevoir. It has been over a year since I last had it together. Carb is a 1b3 and engine is the wv 1600.

I know I am missing a y peice joiner (34) to join the brake servo (pipe 28) to the vacuum resevoir (pipe 32). The Y piece disapeared in the fire along with all the green vacuum pipes. Where does 30 go? Onto the carb I assume. buggered if I can see where though.




No 31 goes to the temp regulator RHS in the air filter but where on the carb. I assume the pipe sticking out from the bottom of the carb in this photo.


If the above assumption is correct why have I always had this pipe go from the temp regulator in the air filter onto the carb? see photo below. Is this correct or is this the missing pipe 30 in the 1st diagram?



photos, advice, free provision of straightjacket woukld be most helpfull.
