Fuel valve selector plastic nut - where to get one?

[vert]

Does anyone know where I can get the fuel valve selector nut circled in the picture below? Maybe you have one laying around and I can buy it from you? Mine is being held with a circle clip and it's very loose so I'd like to fix it the right way. I can also use a new rubber washer and the screw cover, but not as concerned with getting those. I've installed a brand new OEM valve and didn't want to have to buy a knock off kit just to get this washer.

Lots of people should have those. I'll have a look in my pile.

That's great, I was hoping someone has it just laying around! Will pay shipping and a reasonable $ for the part. Thank you.
