I suppose if you're running at maximum power long enough the smaller fuel line could result in starving for fuel.

But I'm inclined to think its not a big deal. You could buy some brass fittings to adapt between 5/16 rubber and 3/8 rubber, but we're only talking about 1/16 difference and your clamp should be able to deal with that unless your hose is way too big in the first place.
