Years ago I replaced one steel coolant line with marine hose, rubber. Greenline I think. This was in my old 82 diesel that I converted to 1800 gasser. It worked fine for the 10 years I ran that van. This was full length from engine to rad. But one caveat, it was only the one line that was replaced, I ran the new line rubber line parallel to remaining steel. It was a tight fit through the body members. I don't think I could have ran two rubber lines.
