Product review (2 stars): Kit incomplete?
Having the same issue as many here where the connectors at either end leak.  Found a 'how to' video on Youtube (http://youtu.be/QrqwfoLHkVk) which looks like he's assembling the exact same kit - except that in the video his kit has rubber ferrules for sealing the back of the connector.  The video is 2007 - did they leave the ferrules out of newer kits? Or is this just the sort of thing that you have to be a pro to know about?

In either case I can't recommend this product.  I don't hate it but it seems incomplete.
