Need info on changing fuel pump on mercedes s500 yr 2000?

I need to change the fuel pump and filter, location, and any how too would help thanks in advanceNeed info on changing fuel pump on mercedes s500 yr 2000?
Fuel pump is in the rear of the car. Should be a black plastic cover over it and the fuel filter. However are you sure its the pump? On that model car the pump does not turn on unless the car tells it that everything is working. Have seen problems with the crank sensor going out. Car sees no signal from it thus it does not turn the pump on. Also check the fuse to the coils they some times blow again the car sees no ignition so it does not turn the pump on.

Start by checking to see that you get power to the pump when cranking. If not look you need to see why the car is not sending power to it. Also do not be shocked by the price of the fuel filter in that car it has a pressure regulator built in dealer list is $116.00
