Pex line size?

[Razorbackfan]

I have a 2013 Landmark San Antonio with a 55Aquajet-ARV pump that’s leaking at the pump head. Can’t find rebuild kits for the pump and new ones are 180 bucks so was going to bypass it and send it off for repair maybe to a marine shop. Anyway I’m wondering what size PEX lines are in the system 1/2” or 3/4”? I think it looks to be 1/2” but I don’t want to buy the wrong size. Thought I would replace some of the lines that are looking old while I had the pump out.

All of the internal plumbing is 1/2".

Thanks, ordered up some line and fittings.

In the online literature for the aqua jet pumps...they say there are no service parts available for them at all. They do say there is a two year warranty.
