Carbon Canister Removal

[ProjectChimaera]

Hi, I'm not planning to refit the carbon canister whilst the body is being refitted. I'll vent the tank with a filter at the back somewhere and it saves running new pipes etc. To the front.
Could anyone advise if I should remove the electronic valve and connect to the wiring? Will the engine management system detect a defect if I leave it disconnected?
I've read the previous threads on this but can't see any mention of the connector.
Thanks

Thanks chaps, saved me some work!

Hi, can't remember which connection is the fuel return to tank?
Is it to the offside rear of the tank or at the neck connection.
I've removed the canister so presumably whichever one of the two is the vent goes via the rollover valve and to atmosphere? I think Steve D commented that this pipe needs to go vertical first before returning to the boot base to exit?

Found a diagram now!

I removed mine the weekend. Can gone, long pipe that went to rear gone, pipe from can into engine bay and onto plenum gone. I assume there is one pipe coming ou tof the gas tank. That just vents somewhere to atmo does it?

Sounds like the pipe you have left is the one from the filler neck to the rollover valve beside it and then a pipe going onward from there? Steve D recommends that this needs to go upwards and then down before exiting to atmos through boot floor or wheel arch. Might be worth fitting a filter on the end to stop rubbish being vacuumed into the tank.

Sorry NO.
The pipe needs to be able to vent both ways.
It must let air out on a hot day as the air in the tank expands.
It must let air in as fuel is consumed.

I don't believe a filter is needed as the pipe will be vertical for about 2 feet and the air movement will not be strong enough to lift dust particles that distance.

Thanks Steve, I wasn't advocating a one way valve as it does need to go both ways. I suppose a filter that breathes both ways does run the risk of blockage where an open pipe won't, I'll leave it off.
