Mine worked fine, no leaks, and only a few minutes to install. I did need to use a metal clamp on one of the HC ports as the nylon clamp was to small. I did go out and buy a couple of metal clamps this morning as I ran out of nylon clamps and can't find any locally. I was going to order some more online but the shipping cost on 10 or less clamps is more than the clamps themselves.
