Plumbers measure pipe as inside diameter. Everyone else measures pipe as outside diameter. Take your fuel line with you to be sure you get the right size.
A tubing cutter and a tubing bender are great tools if you plan on doing this to more than one motor.
You probably have incurred a type of inverted flare fittings on car brake lines. The end of the tube is flared, but the nut has a male thread, while a regular flare nut has a female thread. The 3hp carburetor bowl has provision to accept that inverted flare tube and nut (matching flare machined into the cavity where it goes.)
BRAKE LINES!!!!! Yes!!! I remember those fittings! Frank, thanks for knocking that brain cell loose. It’s rattling around up there just fine now 😆
