I had mine come off. It definately was on tight but I guess with the underhood heat it caused the neck to relax thus allowing the hose to slip off. I took the filter and hose off of the truck and reattached them together. Then I drilled 2 small holes for self tapping screws through the clamp, hose and filter neck. Clean any debris out of the hose and reinstall on the turbo. It'll never come off now and I haven't made the cross sectional area between the filter/hose smaller as it would be with a pipe. Not to say the pipe doesn't work - It's just another way to skin a cat...
