Not your typical vacuum line question. Please look.

[I ask good questions]

I searched this with no luck. Is that vacuum canister behind the driver headlight necessary? If not then what lines to do need to cap off and re-route to eliminate it? Its an s13 with an s13 sr if that helps!

Delete that s*** it's your evap system. It is called the charcoal canister. It just captures fumes from the gas tank and then recirculates it back into the intake. So theres probably 2 lines running to your manifold. The one on the bottom is for the recirculation and that's not a vacuum source.The top one is a vacuum source. So just pop both lines off, cap the bottom one and then you have an extra vacuum source for something

Then for the line that runs from the tank up to the canister I just took it out so my bay would look cleaner. It goes down to a rubber connector down on the very bottom right side of the bay. Just pull it off there and leave it open. I didn't didn't cap it off cause I didn't want it to build pressure in there or anything
