Remove rats nest and keep Charcoal Canister?

can i remove the rats nest and keep the Charcoal Canister? I know that there is no way of passing emmisions with the rats nest removed. But i would rather not smell raw fuel while driving around.

thanks

Found this great description of the PCV system in the archive anyone see any bad side to this?

"PCV SYSTEM - now we're getting complicated . This is the Positive Crankcase Ventilation System, which is there because the oiling system generates pressure which needs to be bled off - it can't be a sealed system. Stock, the system is fed back into the intake, and some residual oil is pulled into the intake, dirtying intercoolers and throttle bodies . On the TurboII, the nipples to be concerned with are just below the oil fill cap, and where the oil fill neck meets the block. The NA's only have the one where the fill neck meets the block (I think). This HAS to be vented - if you cap it up, you will pressurize the crankcase, which can lead to smoking and all kinds of weird problems. Venting it to atmosphere is the easiest solution, but will over time make a mess, as excess oil comes out of the nipple. The right way is to use a catch can that has a filter on it to catch the excess blow-by. Jaz makes a tiny catchcan that works great - Jeg's carries it."

I removed the charcoal cannister and ran a vac line from the fuel tank vent line (the one that used to feed the charcoal cannister) under the car and zip-tied it to the fue lines. I haven't smelt fuel from this once.

I still have my charcoal canister and purge valve...

It's easy to do...The big line from the canister connects to the nipple on the middle iron. The other nipple connects to the big nipple on the purge valve. The small nipple on the bottom of the valve connects to the throttle body BEFORE the throttle plates and the nipple on top to a vacuum source.
