Best Charcoal Canister Solution? Aftermarket EFI

[stradlater]

So, after f'ing around with LPG for all these years, then going EFI, I don't have a charcoal canister, nor do I have the fuel line for it.

I have only recently figured out what the smell is, and hence now I'm asking this question.

I want the easiest charcoal canister solution. In reality I want the easiest solution for getting rid of the smell - that MAY not be a charcoal canister at all.

But really I don't want to be running another fuel line to the front of the car, nor do I want to run another two vacuum lines off the plenum, but it appears that this is the only way when it comes to charcoal canisters.

I did read somewhere that there were a few types, one of which was simply a charcoal canister that plugged into the tank vent line and had not other connections. Can't say I've seen one of those yet.

Thoughts? Suggestions? I'll go to a wrecker to get any sort of canister, the question is really how do I do it with the least pipes?

TIA!

find smallest charcoal cannister from an EFI model (i usually go to the daihatsu or similar small car section) - it will have a drain (goes to atmo), port in (connects to breather @ tank), port out (goes to throttle body). Most if not all EFI cannister have a 1-way valve on the port out and when under boost, it should close off.

Charcoal cannister's have to have at least one if not two outlets as they have to dump moisture via the drain at the bottom (note: they have to be mounted the right way up) and fuel vapour it cannot return to the tank has to go somewhere (e.g. the intake of the motor).

You could mount the cannister up the back next to the tank and just run 1 vacuum line up to the engine bay to a port on the throttle body (has to be post throttle plate or covered up by the throttle-plate when throttle is closed).

Some factory setups put a VSV or electrically-switched vacuum switch on that line (to only open it up when motor is running). I never bothered on the 18RTE and won't in the RA65. If you're running a lot of boost, then it might pay to put a 1-way valve in that vacuum line (or have the solenoid above close when on boost) as the valve in the cannister isn't boost rated tho is able to withstand a reasonable pressure differential across it.
