All right, is there any good 5/16 fuel line anywhere now?

I use fuel line for fuel injection no leaks yet. But my rolls are USA made. Or i just plumb with AN with #4 or #6 braided.
Army/Navy incase ya ever wondered what AN name came from. It does come in black and black fittings.
On one car cut and flanged the metal line so i could put a fitting, it was over kill
