Suggestion: Spring clamps or worm clamps?
When I purchased my Diamond DA20, the previous owner "mechanic" had used worm clamps on all the water hoses. Another pilot/mechanic told me that spring clamps are better because they expand and contract along with the corresponding heat. Then at Oshkosh this year, I got a good look at a new 912 engine and saw lots of spring clamps. However, when I swapped a few clamps out, I could not get them to stop leaking. What clamps are the right ones to use and where?
