So last evening I managed to succeed at getting the oil return lines installed with the new constant tension spring clamps but I failed at using them on the intake tube hoses. I had ordered a bag of 10 ea 7329K18 clamps from McMaster-Carr (the largest size they have) and the bottom line is that they were just too small for my engine and the official Lycoming hoses (new ones). I managed to get 3 of the 4 installed but the clamps were at their extreme open position and I had to force it all together. Never did get the 4th one on.
After all that, I did not want to trust my life to what I was seeing so off they came and the original hose clamps went back on. It was virtually impossible to get the hose centered up on the tube and the intake fitting while wrestling those clamps.
Bob Martin has put me on to a source for some that are the next size larger @ 2.165 nominal diameter with a 1.843-2.283 range. The McMaster-Carr ones top out at 1.969 nominal with a 1.713-2.087 range. The OD of my Lycoming intake tube hoses are ~ 2.23" installed.
Anyone have a source with these larger sizes that beats Amazon on price and delivery?
