    I have a skybolt that first flew in 2002.
    It has a flush mounted non vented fuel cap. I is leaking when inverted. I am having trouble finding a replacement gasket. I spoke with steen and was told the tank was probably made while the company was owned by Hale Wallace. He contracted the tank construction out to a now unknown source. They have since changed to the 1/4 turn screw on cap. The gasket is 3 inches in diameter with a 2 inch hole the proceeds down for 1/2 an inch. 1/8 inch rubber. I have checked with most of the usual aviation suppliers with no results.
    Would anyone have any ideas for a replacement. I don't really want to change the tank set up for something so seemingly simple.

    You can buy sheets of gasket material from the automotive supply stores and cut your own gaskets. Not the most elegant solution, perhaps, but I've saved some vintage motorcycles from obsolescence that way.

    EDIT: Never mind. Now that I see the pictures, flat gasket material won't help you much. :D

    Find a RV guy and try one of their gas caps. Pretty sure it is the same as I am using and it seals in a 2" bore. They are available from Aircraft Spruce. UD-3-C Fuel Cap Only 05-15373 $36.95
