I’m thinking 1/8 inch(maybe 1/4) copper tube with compression fittings. Lowes? Home Depot? Surely Ace hardware. They wouldn’t be aluminium, would they?
Does anyone have an example of this ‘inverted flare’. 20 years of plumbing is not helping me understand that LOL
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.
Hi there does anyone know a source for the solid copper/metal fuel lines for the older johnson 3 hp or can then be made ?
Thanks
Your local auto supply should carry it in rolls.
Tube is measured by outside diameter while pipe is measured by inside diameter. It’s best to bring a sample or your fittings with you to make sure you get the right stuff.

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 😆
