About the Charcoal Canister

 Ok, firstly my car is a turbo 3sgte, so boost not vacuum in the intake manifold.
I believe there is a valve/switch between the purge outlet of the canister and the manifold, but my car doesn't have that valve.
Nor does it have the little jet in the tube (pretty sure this is to stop big surges but is less important than the valve).
Now, one of the tests in the BGB says to ensure you can't blow into the purge port, and mine passes that test.
If I suck on the purge outlet I get some petrol fumes and the car has been off the road for over 6 mths !!
Q1. So do I still need the (missing) switch/valve on the line to the manifold ?
 
 Another test of the canister is to be able to blow into the inlet from fuel tank and the fresh air inlet with little/no resistance.
Mine fails this test. I have to blow hard into the fuel line inlet to get any air in, so it's open but heavily restricted.
Tonight I will try to unstick the valving in the top of the canister with some carb cleaner and higher pressure.
Q2. Should I remove the canister altogether & block up all the holes except the fuel tank breather ? 
 
Q3. Other thoughts ?
 
cheers,
 

Thanks Redd, yes I have and posted on it.
I have decided to put my old canister back in. I have blown it compressed air, tested the inlets and it seems to be ok.
No risk of a vacuum in the fuel tank and no possible reverse flow /boost leak into the purge outlet.
 Still can't see how the canister can cause running problems. (as opposed to a faulty petrol cap breather).
