2003 YZ450F Fuel line size

Ripped my fuel line last night when reinstalling the carb, so I want to replace the line. What size it the ID of the fuel line, is it 1/4" or 3/8"? Or is it another size? I want to make sure I get a good seal on there without having to be totally dependent on the hose clamp, which it will have installed as well.

Thank you in advance,

Damian

The correct size is 8mm (5/16"), although 1/4" will work. The best clamps are the OEM spring wire clamps.

The best clamps are the OEM spring wire clamps.

What makes you say that? I ask because mine have lost tension over the years.

Damian

They loose tension when you over-expand them during removal, or just flex them too many times. Spring clamps are better than screw clamps because as the hose naturally shrinks, a spring clamp maintains tension on it, where a screw clamp becomes loose.

Ok, thank you for the information.
