vaccume lines in passenger fender

[urban96]

since ive deleted the smog pump, lines and EGR can i remove that big vaccume tree thingy on the passenger side? theres only 1 left plugged in (thats visible) and thats right on the nipple on the back of the intake next to the FPR

there anything inside the passenger fender that they connect to? i looked at the vaccume diagram and it looks like its not connected to anything but i wanna double check

The charcoal canister is in the passenger fender, so that's the only thing I can think of that it'd run to without looking.
