Now that you can clearly see everything, you need to disconnect the fuel lines. If you have an in-tank pump, there will be one line on the top of the pump that needs to be disconnected. If you have an under car pump there will be both a line in and a line out. These are also called the low pressure and high pressure side of the pump.
To remove the lines, loosen the hose clamp or fitting that are holding the low pressure side in, then loosen the fitting and remove the line.
Be sure to have something on hand to catch the gas that leaks from the lines so that it doesn't splash the floor and create a fire hazard.
