I order a coil of OEM fuel line from Bike Bandit for a 1982 Suzuki GS1100GL. Has the correct inside diameter, thin wall, doesn't kink, very flexible, not affected by ethanol blends, easy to cut, nice looking, inexpensive, black, and still used at least up to 2017. Use it on my BSA, and my Norton., lawnmowers, yard tractors, etc.

keep your "oddies" lubricated, and carry a dime
