Hey guys

There are the three fuel pipes running under the car, 1x feed from pump, 1x return to tank, and a third one that seems to be for the evaporative canister for emission control. Can i block off that third one or is it serving as a breather for the fuel tank?

Any help much appreciated!
Thanks

 

If u removed your emissions then it's definately free for anything. I accidentally cut that line while doing my fuel upgrades so I guess it's free for anything
