I may have come up with an idea to simplify determining the correct hydraulic hose length when adding a new circuit of if you don't have an old hose to measure. Perhaps everyone else has discovered this before me and I'm late to the party. Anyhoo...
I used a length of 3/4 inch rubber garden hose. It's missing the female fitting because it went bad and I never replaced it. I ran the hose just like I would have run the hydraulic hose. It's just slightly larger in diameter than a 1/2 inch hydraulic hose and the best part is that it will bend like a hydraulic hose and hold the shape, such as if you have to run the hose in a pivot situation, like from the loader down the loader lift arms. I marked the length that I needed with a cheap zip tie, making it easy to measure the length of hydraulic hose that I needed, without being way too long, or worse, and inch or so short. I hope this helps someone in a similar situation.

I'm such a pack rat though so I have a hard time throwing the garden hose away once it's served its purpose. I figure that I'll use it to protect some wires or cable or hose. I've done that too. The local Kubota dealer can't resist the joke that they don't have fittings for my garden hoses when I bring them in.
