Pierburg Carb Vapour Canister

[syncrodude]

The vapour canister on the carburettor appears to be blocked. Anyone know where I can get a replacement ?

What the blithering heck is a vapour canister?

used to live in snorbans

It's a plastic thing sits beside the carb, has pipes from fuel pump, fuel tank vent and a fuel pipe to the carb. I didn't know what is was called until I looked at the Pierburg wiki.

maybe a syncho thing
Wheres the wiki page with it on?

Must be a Syncro thing, but all carb Sciroccos have them. Usually referred to as a "swirl pot".

[syncrodude]

In the wiki I didn't spot the link to the Gower and Lee website before . I've ask them if they have a swirl pot. I do suspect that I have the plumbing wrong, although it' s been fine until now. I've tested it, bypassing and going straight to the carb. Anyone know which pipe goes to top,middle and bottom.

[ghost123uk]

From what I remember when I last "played" with the Scirocco one, bottom = feed from pump, middle = feed to carb, top = return to tank.

Oh, hang on, let me look in my Haynes for the Rocco...

OK, checked, the above is correct

[ghost123uk]

btw, as far as I know, a swirl pot has nowt in it (except maybe a course baffle or two), so any blockage is likely to only be in one of the stubs, or external, and easy to do a "blow down it test" too

ps, unless it's been stood for months with Ethanol type petrol in it =

Thanks ghost123uk. I think the pump is on the middle , will check this morning (a weekend without rain ) , do some re plumbing if necessary and test. I'll let you know. I'm getting this problem sorted before selling.

No Ethanol has been in this one as far as I know , had the syncro since 2006. Before that 2 American ladies had driven around Europe in it ???

I've taken off the swirl pot and blew through the bottom hole which didn't give any resistance. Blew through the middle where it did give some resistance and I can hear some kind of valve operating. So I connected up as bottom to pump out , middle to a container , and sure enough the fuel came through when turned over . Can't imagine why I was getting away with it all this time without problems till now. Thanks for your help ghost123uk.
