Changing fuel pump. connection ???

I have the tank out and everything disconnected other than 2 connections. They are the 2 connections that go to the box located directly behind the fuel filter. How do I unclip these connections?

You squeeze the flat parts inward which pushes the locking tabs clear of the barb. You can see the tabs on the blue fitting in the lower picture... if squeezing them alone doesn't work, you may need to get a small screw driver in there and help it out a bit.
