Vacuum lines disconnected. Destination locations? 91 Passat 16V

[markeysscirocco]

Just bought a 91 Passat with no time to wait on a Bentley for this week and running to a issue with the green and white nylon lines destination locations. Meaning where do they go to? Then I have one larger one that no hose that comes off a 90 deg boot in front of fuel dizzy. It looks like it comes off two valves stacked on top of each other. Thanks in advance! Ill have pics up this evening!

have a look at this one. you need to expain a bit more details.
the 90 degree i think you are talking of the cback of the intake manifold.
the other 22 lines youi mention; one should be the vaccum line to the hvac recirculating flap inside the car by the passenger side footwell; it goes through the firewall at the heater core; the othe rline goes ot the vaccum signal for the cruise control pump on the driver side fender well area behind the battery ; i think.

Well the one I fore mentioned (90 Deg off a valve) goes to the throttle body

Update:

those in the picture are your purge valves. actuated by the ecu to burn up the vapors form the fuel tank.
the grey color round valve has a clear hose coming from underneath the airbox where inside the passenger fender area is located the charcoal canister.
the canoster collects the fumes form the fuel tank.

the black one connected ot the grey one through a black 2" long rubber hose; is the one that when excited by the ecu opens the passage to the TB as you mention before and the fumes are burnt or recirculated into the engine to be used up.

what other hose connections are you trying to solve?

One other thing, is this head the same torque specs as the 1.8 16v head?!
