Be sure you got all of the fittings in the fuel system sealed and tightened properly. Did you replace the fuel lines, too?

Did you have any air bubbles during the lift pump test? Any air is a sign of air leak...

Also you can reverse this... Pressurize the fuel tank with about 1 to 2 PSI at the most and look for wet spots in the fuel lines. I heard of rusted connector at the fuel senders, damaged banjo bolt washers, return line cracks (air leak), damaged pick up tube in the fuel tank, Etc...

It really does sound like an air leak somewhere. That is why I asked about fuel lines. Michael's suggestion sounds like a good one. Pay close attention to connections and the top of the tank. You may want to clean everything up good first, so you can see if there are any leaks.
