Can you borrow a micrometer and measure? I would see if you could bring the tubing back. It most likely was sold to you as 1/4 inch. Can't be if all the fittings leak.
Are your old fittings all John Guest?

Sorry for the delay in responding. They are John Guest, yes, or at least that style.
I ended up cutting some tube already on the unit and using that instead. It stopped leaking. I just needed enough for an RO membrane flush kit.
It's funny Home Depot sells that stuff right next to the connections considering that they leak. Weird. I couldn't have been the only person with that problem.
