Is this part of emissions? Do you guys delete this when you go single turbo?
it’s a little small black plastic cylinder w vacuum lines (looks like it goes toward the fuel tank)? And other end goes to a solenoid (by the throttle).
another vacuum line off of that solenoid looks like it has a check valve of some sort and might have been attached to the upper intake manifold (one of the 4 open ports)
