I said in Post #2 that I didn’t receive the “rub strip,” but I was wrong. Now that I know the part number, I rechecked my inventory sheet, and the F-01204N did ship with my fuselage kit. F-01204N is actually called a fuel tank pad and is listed under sub-kit 5. It is shown on drawing 21iS/U-01, but I didn’t see where it is installed in the written instructions.
A note on drawing 26iS/U-08 says the fuel tank will be in and out of the fuselage while installing the fuel system, so perhaps the F-01204N tank pad is installed when we mount the fuel tank for the final time.
The smaller F-01241 fuel tank pads are match drilled on drawing 21iS/U-02, and there is a note on drawing 21iS/U-03 that says you can delay installing the F-01241 pads until after painting the interior. My guess is that we install the F-01204N after painting, too.
