    The Gulp valve is not connected to the carbon canister, or at least it 
should not be.  The gulp valve has an input, an output and a vacuum connection. 
 It can only be mounted such that the vacuum connection points away from the 
valve cover.

Then the input connects to a hose that has a restrictor inside it, this 
connects to the air pump. The other side of the gulp valve connects to the 
inlet manifold.

I think you must be talking about something else, perhaps the ANTI-RUN ON 
valve, located just below and ahead of the carbon canister? Is your car non 

If you are referencing the ANTI RUN ON VALVE, this is connected as follows:-

It has a vent hose that goes down below the car and is open to the air. It has 
a hose that connects to the carbon canister and a small hose that connects to 
the manifold vacuum. Hope this helps.
