I removed my carbon canister system and the 2 valves on the fuel tank i have just left as are, with no pipe work, venitng to atmosphere.

Am i right in thinking that these valves only open when a certain pressure is reached, or are they constantly open?

And does this mean fuel left in the tank will eventually evaporate if they are always open?

Thanks

Mines in the bin, not noticed any difference. Is your newage?

Mines a classic, hmmm maybe i just didn't have any fuel in the first place lol.

Thanks

Mines been launched too, sometimes it seems like the fuel
Evaporates looking at the gauge

Hmmmmmm, the only point is could evaporate from is the valves that originally had pipes coming off in which the vapores traveled down to the canister, wonder how the valves work?

Thanks

Sorry, meant that as a joke in that it uses **** loads of fuel

Haha, should be a comedian lol.

Thanks

What is the benefit of removing it?

Mine was for simplicity of my fuel system on my track car, as for a road car, none i don't believe apart from space.

Thanks

Mines been binned as when I removed the towbar I had nothing to bolt it to! Plus I'd already binned the purge valve and solenoid from under the bonnet to simplify fuel system and pipe work.
