A mate of mine has just bought a ‘77 Mini S (1098) and it has a small charcoal canister on the drivers side. It has 3 hose connections on it, but 2 of them have the one line looped to them, and the third looks as though it’s going back to the fuel tank. Is there any issue in removing this altogether and venting the fuel tank to atmosphere? It has twin 1 1/4 SUs fitted.

That'll work. 

 

I haven't heard of cars that early having such a system, but note you're down under.

 

Perhaps it was doctored for the twin carbs? You'd expect it to gather the carb & tank vents & feed them to the induction system via a control valve of some sort.

 

The tank must have a vent somewhere, possibly in the filler cap.

It's redundant these days. It was fitted to capture fuel vapors back in the day as there was certain chemicals in those vapors that contributed to the photochemical 'smog' that can to give the sky that orange haze, though, I never saw that anywhere in Australia, I did see it in a few major cities in other countries, Jakarta was the worst, I though the sky was on fire !

 

I'd suggest fitting a sealed fuel cap (if you can find one) and use that return line that the Evaporative System has as a fuel tank vent. That should reduce staining of the paintwork around the filler cap.

Thanks guys, very helpful. He’ll be pleased to get rid of it.
