Fuel line size?

Recommended Posts

Quick question: '05 YZ250- does it take 1/4" ID fuel line? Does that work on the petcock -> carb, and carb vents, too?

Thanks,

We do not have a consensus!

I'm looking at the colored fuel line on that auction place. Well, it's daylight now so I'll go down to the barn and measure mine with a drill bit. I'll report back...

The fuel line is 7mm

fuel cap vent line is 5mm

carb vent lines are 4mm

and the radiator overflow is 6mm.

1/8" id for carb vent lines

1/4" id for fuel line works...but it was tough to get on.
