Anyone here used these? Lots of options between Amazon, eBay, and McMaster Carr. Looking for anyone with experience using these that can recommend fittings and hose that works well and lasts in the underhood environment, and is decently flexible and doesn't turn hard as a rock in winter.
Here's kind of what I was looking at.
