Dialysate flow rate when pulling through a jug

[LoveScience]

TL;DR Summary

Looking for an answer and explanation (with formula) to understand the physics concept behind what tube would fill faster which same speed of pump (drawing up not pushing fluid through

Friendly argument at work (both non physics majors) with what tube would fill up faster with a flow rate (siphon like) that remains the same through two different diameter tubes. The dialysate jug is open to atm pressure. One tube is about .5 inches in diameter and the other is .25. We were agruing which one would fill up faster with dialysate through the tubes that are similar in length. The tube is drawn in black and is only approx 12 inches in length

None of the medical guys have jumped in yet. I would have thought capillary action would play a part

what tube would fill up faster with a flow rate (siphon like) that remains the same through two different diameter tubes

If that statement is true, I don't see the argument being about anything .
Might as well argue if it takes longer to fill a gallon jug or a pint.

With the same flow rate in both tubes the ones with less volume fills up its 12 inch length first.
