Do I need to worry?

Oldbikefixr doing the non-OEM tango apparently worked, but it wasn't nearly as easy as OEM. They seem to be backordered like a lot of parts, but maybe CMSNL has some, or eBay. There is one line that goes from the water pipe to the thermostat housing that you can prob buy from a bulk role at your local shop. Otherwise the bulk role will have a ton left over if you buy it. It's not a fitted line and is probably more prone to being worn out than the others.

I'd probably replace the insulators if they were even just 5-6 years old unless the bike sat a lot. One air leak and you've got issues.

yeah, I bought the Honda 5.5m length or whatever it was, and then gave it away in 2ft lengths for a few years to anybody who asked on the forum. I finally ran out in the last year or two, I think I bought it in 2013.
