From memory once the connector is off you carefully remove the yellow capping inside the connector as shown in the pic. Once the capping is off it will become clearer.
You need to get a tool that is very fine. I have propper terminal removing tools however you could probably use a needle or fine split pin if you know what I mean. You will see when looking at the terminal from the inside with the yellow cover removed where the locking tab for the terminal is. Once the locking tab has been depressed with the fine tool the terminal will pull out of the connector block from the back of the connector (towards the engine so to speak). I have no doubt that you will feel the forward and backward movement of the terminal.
The terminal locking tab will depress easier with the terminal pushed into the connector as it takes the pressure off the locking tab. Once you are happy it is depressed leave your fine terminal tool in place and pull the wire gently out of the back of the connector, pulling the wire and terminal clear of the connector for inspection.
Note : It is not abnormal for the terminal to move a small amount inward and outward when fitted to the connector and the connector pushed onto the pump. However if it is very easy to move in and out you can assume that the male and female sides of the terminal are not a firm fit.
Hope this is all clear, its a bit hard to describe. Oh and be carefull if you are going to do this as I don't want to be held responsible for anyone bastardising their connector trying to get the terminal out of the connector.
Good Luck
