Oh okay i think i know where you stand now that you mention the swiftech bleed valves. All Swiftech products use 1/4" ID hose. You can ignore the OD values as they do not matter. Because the hose fits, this leads me to believe that you have 1/4" ID hose. The pump u said has 1/2" OD... you should measure its ID. The Black Ice is 3/8" ID. 3/8" ID is standard. What size ID fittings does the waterblock have? If it is a swiftech, they'll be 1/4" ID and if they are any other brand, they will be either 3/8" or 1/2" ID. So here's what we know...
We know your hose and bleed valves are 1/4" ID.
We know your Black Ice radiator is 3/8" ID.
We need to know the ID of your pump barbs and waterblock barbs. Then we can further instruct you here...
