    Its a vent line that goes to the charcoal canister but it wouldn't cause the car not to start. Mine is sitting the same way cause I dont have a charcoal canister. Just connect it when you put the new one in.

    Will not having a charcoal canister give you issues? Mine got pulled during the engine swap (still have it, but there is a battery where it used to sit)

    No, I havent had mine for a couple years now. The canister was there to help use the extra fumes to give better emissions. I would pull the line off the gas tank so it doesnt vent through the line all the way in the engine bay and you wont smell so much gas under the hood. It really smells when you are racing or hard on the gas. You running two batteries?

    85 FC, that undercarriage looks super clean.

    Ummm .......... NO ! The EVAP system (emissions mandated) uses gas tank vent line(s), solenoids, charcoal canister, and intake manifold vacuum to burn gas vapors stored in the canister during shut-down soak periods. After the engine warms up, goes to closed loop monitoring and the running conditions approach a steady highway speed, the system opens the charcoal canister to intake manifold vacuum to purge the canister of stored fuel vapor, thus burning it in the intake charge. Yes, it burns the vapor; no, it's not a gas mileage booster. Emissions only - and different engines/years use different versions of EVAP control.

    I do not have dual batteries, but the alt on the 350 was on that side of the engine bay, so the battery got moved. The line was removed back to the fuel tank, I believe.

    All Cadillacs should have at least seventeen batteries.
