General remove charcoal cannister?

[cinqen]

I'm currently in the middle of putting my car together (engine swap) and I noticed that the blue pipes to the charcoal cannister are clogged (see pics), which makes me wounder if its of any use at all.

Could I just removed it and plug the pipes? Any known sideeffects?

I would be intrested to know to! about a week ago while replacing my horn I disconnected the plug that goes to the charcoal cannister valve(?). So far Ive had no probblems.

AFAIK, the valve releases the vacuum that builds up in the tank as fuel is used.

really?? Almost used a whole tank and so far no probblems! would of thought the releses would of been closer to the tank (or on the tank)

Might connect it up and see if i hear anything HISS

IIRC, theres a one-way valve on the top of the tank that stops fuel getting out and lets air in. this valve is piped through to the charcoal canister (via the electronic valve) and then to the inlet on the engine so as to not vent any fumes into the atmosphere to keep with emmisions regulation.
I expect theres some sort of mechanical pressure release built into the system somewhere to prevent excess pressure build up should one of the valves fail.

humm thanks for that. when i do my engine swap i might trace where they go and snip it all off! the braket on mine is in worse condition then cinqens if anyone asks it fell off

Hmmm, Are you sure? I'm no expert but.

If this were the case then the Fiat Phart (when fuel cap is removed) wouldn't exist. I think you'll find that they're there to feed vaporised -> liquid fuel in the canister either back into the tank, or the main fuel feed depending upon the fuel system setup.

I could be wrong, But I doubt it's different for the Cinq/Sec than it is for other cars.

I'm with panda. I thought it captured excess fuel, condensed it and fed it back to the tank.

There is a pressure releif valve at the tank end that stops the tank pressurising too much

The canister is plumbed into the top of the tank and captures the vapour, the vapour if then fed into the engine and burned at certain engine conditions ie no load throttle closed.

If you remove he canister the fuel vapour will just vent through the pressure releif valve directly. Not enviromentaly friendly but does no harm to the car
