Thank you! What effect does it have if you remove it.

You tell me bud !!!,Mine just sits there ticking away in the corner,Emissions anyone?? sorry thats my limit with this.

It can throw up a fault code if you dont fit a resister and vent the fuel emissions out through the arch

Is that what the pipey thing is in the bottom? Just a breather? Nothing connects to it??

What's the benefit in removing?? Is there point? I started it without it, just to see what happened...it's sounds lumpy as hell...really rough...

It's all back in now lol

Its mainly removed to remove all the vac hoses to stop leaks.

Copied from somewhere

In a nutshell, the vapor canister was designed to "catch" le fuel vapors when the engine is turned off and just sitting there, so the next time the car starts it sucks them back into the engine and uses them.
it is an "emissions" thing, you don't really need it to run, it's just there to save the environment.

Ahhhh ok then! That explains it. Thanks :-)

prob would have ran lumpy if you didnt block the vacuum
