Leaking Liquid Connector

[DamnRedhead]

Hey all,
Recently finished building my new keezer, and added a keg of carbonated water; I keep the water at 30 psi (with a flow control faucet) and the beer at 8psi. I've noticed that two ball lock adapters are leaking on two 30 psi kegs... double checked washers and everything else... any reason why these connectors would be leaking?

I've read I may need to go up to 25 feet of line, however I thought the flow control faucet would accommodate for this.

Where are they leaking from - where the connection is being made to the post, or through the seal at the top where you can open the connector with a flathead screwdriver??
