Yep ! Everytime I ride fuel will come out when going up really steep trails. I would not tie in any line to the airbox that dumps hydrocarbons in it. A good way to start a fire . All it takes is a stall and a good backfire and your bike could become napalm .Be aware that in some situations you can get raw fuel out of the vent line.
