Fuel Petcock rebuild

[aerologic]

I feel goofy ( ) for asking all the questions but I guess I'm the noob.

So I rebuilt the fuel petcock with a kit that I got from Sam. There was a small o-ring that I don't see in the Parts Catalog. Where does that go? Is it part of the petcock assembly or did it just fall off of Sam's shelf?

I called Sam. He told me where the O ring was. A few days ago I was poking around the plunger but I get nervous. I'll replace the O ring when the new fuel level sensor arrives.
