4′ x 1/4 ID (6.4mm) x 3/8 OD Fuel Hose Line Mx ATV Dirtbike (Clear Purple) 1/4in ID x 3/8in OD

I love the color of it because it matches what I am doing with my minibike but the inside diameter seems a bit larger than 1/4 inch. I used it on a Mikuni 22mm carb and had to clamp it (as seen in the picture) to keep it snug. Nothing I couldn’t work around. I would by it again and just do the same thing I have done.
