You can remove the canister and hoses, but you will need to cap off the fitting on the fuel tank and get a vented gas cap. You can get the one from Wheeling or just order a 49 state cap. The rest of us have vented caps. The California cap is non-vented. If you want the stock look and the ability to lock the cap, you will have to get the 49 state cap. The Zeta cap from Wheeling is nice looking but the cell phone antenna is just stupid looking IMO.
The 49 state cap part number is 3D7-24602-00-00
California cap number is 3D7-24602-10-00
The other hose from the canister goes to the throttle body. You will need to cap that off so you don't have any vacuum leaks.
