The gas valve that turns the gas off from the tanks leak where the stem comes out of the valve by the packing nut.Valve part number 3640-A, I tried tightening the packing nut but that doesn't do it. Is there suppose to be some king of packing material around the stem for a seal? Or what do I have to do to get it to stop leaking?

There is packing under the packing nut. I have repacked them with water pump packing, but I have had to keep tightening them to keep them from leaking. If any one have a good packing to work with gas please let us know.
Thanks

Hello,
If you can, check with a outboard shop that repairs some of the older Johnson or Evinrude outboard engines. The carb needles used packing on them. I know that gasoline will not affect them. I think that these packing washers would work on the shutoff valves.
