Removing The Fuel Vapor Canister

[morbsy]

Hey guys

I need to remove my fuel vapor canister as it is in the way of my intercooling pipes, i've looked all over google on "how to's" but cannot find anything worth reading. so i thought this would be my best bet

I've followed the 3 hoses around, ones a vacuum hose, and the other two dissapear underneath the car somewhere. When i remove this, can i just plug the vacuum line? and what should i do with the other two hoses?

All help is greatly appreciated, thanks guys

Why dont you just move it?

IIRC One hose is the vacuum signal to operate the valve, one is plumbed into the intake somewhere and the other will go to the petrol tank.

You can get hit pretty hard for disconnecting emissions equipment, so if its a street car much better to just move it as suggested.

Plug/remove ever single line up except the one that comes out of the petrol tank. You have to leave that one venting to atmosphere, preferably with a one way check valve.

ok thanks guys, i will re-locate if possible. but if not possible is the hose from the fuel tank the thickest one?

[PM-R33]

From the carbon canister its a rubber hose that goes to a solid hard line. This solid hard line goes along the firewall behind the engine, then down the drivers side along the solid fuel lines. Right at the back of the car in front of the RHS wheel you will see these lines going back up towards the petrol tank. The solid line will go back to a rubber line. Disconnect it here and just vent it to atmosphere or as i said, a one way check valve would be ideal.

But which way would you have the check valve? It meant to be able to breathe in and out, as the fuel is used and expands with heat

[PM-R33]

Hmm interesting, never thought about that.

You would have the check valve so if fuel flowed out, it would close up.

The check valve won't close up from air movement, too slow, not enough force. If it were a change of say the tank being pressurised 50PSi, then yeah, it'd close, but not from heat expansioin.
