    Wanting resurrect this topic.
    So which way is this supposed to be? I have a 14 year old spectra premium cr9c tank. When looking at the tank from the front of the car looking to the rear the first vent line (left) is the short one, the one on the right is the long tube. The previous owner of this car had the short candy cane vent line that goes up near the shock mount hooked up to the short line in the tank. Is this correct?

    Yes you’re right, sorry for wasting your time.
    I found old file photos of my original 69 tank and an NOS tank bought from Mopar in 1996. Inside the tank, long line closet to the sender, which the short line outside is hooked too. It’s just that this spectra premium tank messed me up. I will reverse the lines from the way the previous owner had them hooked and should be good to go.

    He also put a 3/8 pick up with 1/4 return sending unit in it. It should be fine to just block the 1/4 return for my 69 application, correct?

    Yep, just cap it with a rubber plug and clamp.

      Just a thought has anyone installed a vent in the filler neck and then run the line to one of the vent lines you have. On heavy haul there is a vent in in the filler neck a 3/8 or 1/4 line back to the tank or into the atmosphere. Fuel caps not vented and line returning to the tank allows over flow and smell to stay in the tank. Just a thought good luck.

        Characteristic. Mine runs as high as the rear shelf. They don’t like to be parked nose down.

          That wouldn’t be a vent then. You described a closed loop.

          You are correct. But finding this on heavy haul with no problem leakage. But you can always plug the second vent then run a hose from the neck to the front of the tank or wherever you wish to put it. For heavy haul it works like the overflow tank on the radiator just without the tank. Pressure builds up fluid up to the top back down the little hose back into the tank.
