Adding Residential Sink/Supply Lines to Manifold/Manabloc Plumbing Pex

[kds4]

Does anyone know what size pex tubing is used in the manifold/manabloc plumbing system? I was thinking 1/2" but am not sure. I have a slight leak at the pex connection to one of the bathroom sinks when I turn the faucet on. After watching this video of a similar situation, I'm thinking of upgrading to a residential sink and add flexible mesh supply lines but I will need to add an adapter on the end of the pex line where I cut/shorten it. https://youtu.be/wD22z_aH2OA

I replaced the RV vanity taps and the kitchen set with residential taps .

In the kitchen I had room to use a pex clamp tool; in the bathroom it wouldn't fit , so I had to use the tool to clamp a short piece of pex to a shut off valve, then a shark bite connector to the factory pex.

DW has picked a Delta faucet to go with the upgraded dual-head Delta showerhead I already installed. https://www.lowes.com/pd/Delta-Hydro...ead/1001307140.

I just need to measure to ensure this faucet will fit with no clearance issues with the medicine cabinet. https://www.homedepot.com/p/Delta-Ch...38163-23-12140

If my residential supply lines aren't log enough in the vanity to allow use of the pex clamp (my plan as well), your shut-off work around will be a good plan B. Thanks.
