You really don't understand, do you John? The process to approve this part
is NOT a simple 337. A 337 means you have approved data to make the
modification.

Oh, no, sir. You submit a request to the local FSDO inspector, who transfers
it to regional engineering, who passes it on to Oklahoma City, who bucks it
up the ladder to Washington DC for a policy decision, while you wait, and
wait, and wait for an answer.

This is a frikkin' low horsepower single engine airplane out of the 1930s.
If the valve the person is suggesting that they use is available at the
local hardware store, it is far superior to ANYTHING that was available in
the middle of the last century.

Put the sumbitch on and keep your mouth shut.

If you were to replace the fuel shut off valve with
something not certificated for that aircraft you would need a Form 337 to
gain
approval.
