to take the seat out you have to pull up on it hard. before u start connect the neg. side of the battery. open the gas cap to help to let the or some of the pressure out of the tank.remove the fuel pump cover and unplug the electrical connector and disconnect the wire on top of the fuel pump. disconnect the fuel supply and return hoses from the pump. be careful when trying to unscrew to screws you might have to tip on them to loosing up the lock tight that was put on the screws from the factory. than carefully lift the pump out. disconnect the electrical and move the hose clamp clear the pump fitting. remove the band securing the pump to the bracket and bracket at the bottom of the pump with the rubber mount. remove pump and always remember that gasoline is extremely flammable so take extra precautions when you work on any part of the fuel system. good luck.

The fuel pump is in the fuel tank. You may be able to access the fuel tank by removing your bottom rear seat cushion. If no access there you must remove the fuel tank. If you have to remove the tank and it is mostly full you should siphon out as much fuel as you can into appropriate containers.
