What I did is that I just took a coat hanger, cut off the top and bent it straight. Then, I re-bent the coat hanger in the shape that I would need a radiator hose. I measured the tube's diameter, then I went to napa with my now shaped coathanger, and went in the back where they keep all the radiator hoses and just found one that was shaped like my wire. In my case, the wire matched up well with a segment of a larger hose, and I just cut the hose as needed to get the length and shape I was after.
