I dont have my EGR or smog pump anymore and I'm in the process of cleaning my engine bay up so I'm hiding wires and getting rid of stuff I dont need. All of the smog/EGR vac. lines are going to this black thing. Can I take the whole thing out, or can I only remove the vac. lines and leave the other things there and plugged in?
