Mike, we had the same thing happen to one of ours. It’s seems to be a matter of over tightening the hose clamp. They fit very tight anyway, so just be very gentle with the screw driver!
The spec filter hardly needs a support. They are TINY!
Though it’s probably illegal, we trimmed off the split piece on one of ours and stuck it back on. Works fine. I don’t know why I bothered, we have two new spares in the tool box! And I suppose if we were going to a race where somebody cares, we’d put a new one on!
