gas tank vent?

Do you still have the canister? The best thing would be to keep the canister so the tank can vent fumes through the charcoal. But if not, then you can make your own vent. I put in a new tank, the one with one vent line. I bent my own vent from 1/16th ID tube. Important thing to do is to loop the vent line higher than the filler neck (gas cap). I drilled a small hole, place a rubber grommet in it and ran the tubing into the trunk. I ran the tube up the inside wheel well, into the C pillar, and back down and out the rubber plug that empties inside the rear frame rail. I placed a small filter from a mower on the end of the line using clamp and a small piece of rubber line. I fed the line down inside the frame to a place just in front of the rear spring front hanger. Easy, inexpensive, and effective.
