Charcoal Canister Delete

I am deleting the canister. Would attaching one of these where the canister hose entered the standpipe work in lieu of a vented cap? It seems like it would keep the tank from becoming pressurized or in a vacuum state.

Sell your parts to rfpowerdude - he wants to ADD a canister!

There's a stock part that is a essentially the same. I'm sure there's a bunch of variants. You just want something that fits the hose - I'm fairly certain they are 5/16" but they might be 1/4" - and has a check valve so it closes if it goes upside down.
I'd recommend disconnecting all three vent hoses from the tank and put roll-over check valves on each of them, or run them together into one and put one check valve. You can just run the hose up 6" or so into the hump for the axle and retain them somehow. You can just run open tubes, but that gets really exciting if the car ever rolls over.
Don't use the vapor canister that's behind the rear seat where three vent tubes from the tank run up to that can then one hose runs forward to the charcoal can. The original design had vapors collect in there, then the charcoal canister pulled from it. If you leave that in place then gas can collect in there and it would be difficult to loop back around and get higher than that canister.

From what car are you deleting the charcoal canister?

I would want to replace that anyway since it is likely REALLY old. I am looking for all of the associated hardware that goes with it. Mount for the canister mostly. Any other hardware related to mounting it, etc.

I might still have the mount. I can check if you want. As long as you pay to ship it, you can have it.
