If you did that, then you would have both positive and negative pressure in the fuel tank... theoretically as much as positive pressure as what the turbo puts out. Pretty sure you don't want that
I'm trying to figure out how to delete the system properly - ideally a valve that only works when under negative pressure to deal with the fuel evap issue; I need to remove the solenoid.
