Fuel Sender Gasket

[Ernie Martin]

Yes, Ed, it does depend on the model. Since I know yours is a '73, the picture in my message is from the parts manual for a '73.

Thanks you guys....my shop only had the "cork" like gasket in stock and being that my plane has been down for six weeks, I was done waiting for parts. They installed the gasket with some sort of little rubber type washers around the six screws I mentioned so I will keep my fingers crossed that it does not leak. I guess my shop felt the leak was through the holes for the screws as opposed to the gasket itself so we'll see. My plane is back in my hanger as of today so hopefully I will get a chance to fly this weekend or early next week.

Thanks Ed

So, does anyone know the part number for gasket in the fuel selector valve in the wing?

[Ernie Martin]

I looked for the gasket in the fuel selector valve in the wing. You can see the gasket in the illustration, but there is no part number, so it must not be available separately. Notice that some of the other parts come only in an Airborne kit.

I see the same thing, why does Cessna do that. Has anyone ever rebuilt one of these selector valves with an airborne kit...and has the gasket part number handle?

The number is listed in the O-2 Illustrated Parts Manual, it is B3-12-1. I looks like it has six screw holes plus the large hole in the center.

Thanks, that's some good info. Why would the military get that kind of info but not the civilian? Now to find a supplier for it. The usual suppliers don't list it. Any ideas who might have them?

These are non-procurable parts. Cessna has no availability of these parts. They offer overhauled units for $2,861. If it was just the cork gasket I needed I went to the local auto parts store bought a roll of the fel-pro gasket material of the same thickness and proceeded to rely on my first grade arts and craft days to pattern and cut out new gaskets. I’ve seen other mechanics seal them with pro-seal or B2 but I was always leery about the sealant getting into the selector. I opted for making new gaskets.

Just replaced one of mine. Original was cork as was replacement. My old one had shrunk enough that the screws could be turned by hand. Only the safety wire was holding them in. The original gasket lasted 38 years.
