Ford uses special spring-loaded disconnects on the fuel lines from the tank to the engine, because the fuel pump is in the tank, and the lines are pressurized to a fair amount of pressure. There are special disconnect tools available from any auto parts store, but before you go yanking those lines loose, you need to relieve any trapped pressure from the lines. If you don't already know how to properly and safely do this, I strongly recommend you take the car to a professional.
