72' Emissions Vacuum Routing Diagram?

[88Ironduke]

So I am reading a thread that popped up earlier today... http://67-72chevytrucks.com/vboard/s...d.php?t=662158 Now the small quandary must be answered.

I have deleted the super cool transmission controlled delayed spark-o-matic emission system from my C-10 250 I-6/3OTT. My gas tank is an EEC gas tank, I have the charcoal canister and no lines going from the tank to the canister let alone the engine vacuum routing to my mono-jet (MV) carb. I have power brakes and manifold vacuum going to my HEI distributor.

I'm hoping some one would have a scribbled diagram showing that after nuking the TCS system/wire/relay or know a bit about the system. My carb does not have a fuel bowl vent that I can tie into. Is the fuel bowl vent line required for the canister to function correctly? I can see it being a novelty to operate and purge fumes.. But it seems that it may not be necessary to run since the fuel bowl is vented to atmospheric air pressure. The other two ports seem to be routed to ported vacuum sources and manifold vacuum sources respectively.

Any thoughts on the subject.
