Quick help needed for a basic phoenix mlc aio mod

[jEBIVETAR6]

Got a mlc Phoenix aio from ekwb. Want to change the god damn ugly black tubes and remove quick disconnect from it completely. Got some high pressure high temperature resistant silicon tubes. Ended up with a wrong dimension i think. I got 9mm inner diameter/13mm outer. Do i need bigger diameter tubes? Or can i go with 9/13. Will it cause waterflow restriction/ back pressure on the pump or increased pressure in the lines? or do i need the exact tube size? I think its 10/15mm?

Tnx in advance.

9mm inside diameter is fine for most water cooling purposes, but you will need to buy tubing that matches your fittings. Have you looked at how the current tubing is fitted? From photos it doesn't seem like it's removable - proper modular water cooling parts have fittings you unscrew to release or secure tubing.
