So I'm rebuilding my dual tank fuel selector valves (aka Selectrol 6795) on my 74 C20. So far so good. Have them cleaned up, got rid of any rust, got new rubber O-rings for the selectors, and now I'm ready to re-assemble.

Question is here: lubrication for the selector arm shaft and then the contact on the metal plate to help the selector slide from side to side.

While it should now move much easier now that I have it cleaned up with new O-rings, I'd like to apply some lubricant, at least to the shaft arm. I'm thinking lithium grease should be fine, as I kind of doubt it's exposed to much fuel. And then I'm thinking there's not much I can do about the metal plate contact, other than polish it so it slides better, which I did.

Thoughts here?
