fuel and brake line separating foam suggestions

Looking for suggestions. What did you use for the foam that is recommended to separate the fuel and brake lines as they pass along the cockpit floor? I'm building an RV9A. Thanks

On my 6, I ran a fuel line on the floor tucked against the floor angle. I was worried about chaffing/wear, so I used the thick vynal cable wrap (the kind with the helical cut) around the fuel line. It has worked very well and has a decent look (mine is exposed).

If you are using the aluminum tube, maybe cut a couple of 1" ling pieces of old air hose, split, and put them over the tube. I did that first, then ordered a set of fuel lines from Tom.
