Installed the first of two filters tonight. It dripped at the entrance no matter what I did. I transplanted the tubing, inserted the blue clips as instructed, it was still flowing. Then I opened the other of the pair and it did the same thing - it was leaking in the intake valve. Insert the native filter that has been modified, no leaks. So at least my technique is not a problem. I will just go back to buying the original brand even though it was twice the price.
