Gas Tank Vent

The nipple on the filler neck is connected to the 1/4" metal line with a small piece of rubber hose.It just goes out of the trunk area either into the frame rail or ...somewhere under the trunk floor.Just vents to air.Before putting it back together,remove that metal line and flush it out.Mine needed to be drilled at the top because it was clogged.Spray carb cleaner thru it to be sure you'll have air flow.Hope this helps,Bob
