Kamoer X2S water change pump tubing size

[oldmonk]

Hello
Recently i purchased an open box kamoer X2S water change pump. Now since the pump will be located a bit away from the sump and mixing station, i am looking at getting some extra tubings for water change pumps of X2S.
Can anyone help me with the tubing dimensions? Like internal / external diameter? Kamoer manual doesn’t seem to have that information.
Thanks in advance

I don't have one yet but still comparing the X2S vs the X2SR, I have read that the X2S can use 1/4" RO tubing but because of the increased flow rate of the X2SR 3/8 RO tubing is recommended.
