Richard, thanks for bringing it over here to the list. That was me posting.
Here is the video of what happened as I was about to start on a few hour
trip:

I quickly shut off the engine and went around tightening the clamps. After
screwing then down, the leak was gone and I was on my way. Otherside also
seemed loose so I tightened those down also.

My main question is should I be using a different style clamp in those
locations or just assume they will vibrate loose every so often. Either
way, I’ll be staying on top of those clamps as part of regular and routine
checks.

Jim
