It's closer to the outside diameter of the rubber lines you're expecting to see there.
Knowing what the lines are for I think 5/16" is way overkill, so that would look weird to me.
And third you said you have some distance to run them and 3/16" lines may look flimsy and or need more support than 1/4" lines.

You did ask...
