Removing EVAP system basically.
Ok, you can. But, if you idle for a while it will throw P0441 CEL as you've ditched the carbin cannister. You can get rid of all the associated hoses from the throttle body as well.
You will be left with one hard line which used to go to the top of the cannister which you should put a length of vac hose onto and drop down into the wing to disperse the vapours.
Its a pretty easy thing to do really. I've been running without EVAP for about 10 months now and the only
problem i've had is the P0441 CEL which i cant get rid of.
