I have a 1993 Jeep XJ Sport with the I6. In order for me to get plates in the state of Arizona, I need to pass emissions inspection.
I can't figure out the line routing for the damn vacuum lines. At first, it seems deceptively simple. The vacuum diagram sticker which chrysler corp put on the firewall is fairly cut and dry: two rubber lines come off the rollover vent valves located on the fuel tank, which merge and connect to a hard steel line which runs along the frame rail, comes up under the hood, connects to a single rubber line which runs across the firewall, which then connects to the charcoal evap canister. But there is no where for it to connect to the canister. I found the rubber line dangling behind my cylinder head.
The charcoal canister has two obvious connections: one goes to the air cleaner, and the other is a twiglike hard plastic vaccuum line which runs to the intake manifold. This is all correct according to the diagram under the hood.... but I still can't figure out where the fuel tank vent connects! the hose has no where which it will fit.
two of the three ports on either side of the canister appear to be intentionally sealed shut from the factory with plastic, and the third, also capped port is gigantic, too large for the tiny rubber hose.
Can one of you with a 1995 or older XJ (pre purge valve, pre leak detection pump) pop the hood and help me figure out where the damn fuel vent hooks up to the charcoal canister?
I just moved to AZ from NC, my whole life is on hold until I get plates put on my car.
