Normaly, you have one rubber hose from the canister to a vacuum point on the intake manifold. This point should be at the throttle, and only have vacuum when the throttle is opened a bit, when a small vacuum "leak" would not make a big difference. If it is just pluged into the manifold - full vacuum, the air "leak" may upset idle.
To better control this some cars (XT130 I think) have a small tube from the canister to the throttle only as a signal to open a bigger tube from canister to main manifold.
Other cars have a electric switch controled by the computer to let air from canister to intake manifold, which will normaly only happen with the throttle opened.
Other cars, like NCP10 Echos, have this computer controlled switch paulsed letting a bit of air through with small throttle openings, and more with full throttle.
The 4A-GE 20valve has a vacuum port under each throttle letting a small amount of vapour from the canister through at all times (via mini restrictor valves and filters). In adition to this, it also has the cpmuter controled valve with lets alot of vapour from the canister to main inlet manifold under cirtain conditions (open throttle).
All cars built for racing that I have seen have the charcole canister, and PCV systems removed. The idea is to not let any unknown gasses be given a chance to stuff with the motor in any way. I simple motor is used only, no vacuum tubes unless realy needed. Just a couple of big breather tubes to a catch can.
In this case, should we block the vapour line (which may preasurise the tank), or leave it venting out?
I can't see why the vapour line can't be used as a return. I havn't heard anything against doing that.
