Both the fuel pump and the fuel level sender are located in the fuel tank and are accessed through the spare tire well in the luggage compartment. There is a panel in the rear of the well that is secured with ten M5 screws. Remove the screws and take the panel away to reveal the top of the pump and its associated assembly.
NOTE: The 10 screws are threaded into aluminum Rivet Nuts P/N SP10611 embedded in the fiberglass. It is quite common for the screws to freeze into the aluminum and refuse to come out. The Rivet Nuts will just spin in place. If this happens you will have to grind or drill off the head of each screw to get the cover off. Once the panel is removed you can finish the job and replace the bad rivnuts if desired. A special Rivet Nut application tool is recommended but they can be replaced using 5mm hardware.
Removal of the pump starts with removing the large band clamp around the boot. The pump can be lifted up a few inches to inspect the tank, but to remove it the hoses need to be disconnected from the bottom of the pump and from the return hose tube.
A few inches forward is the tank sender. It is secured by a threaded knurled ring.
When faced with the necessity of changing the pump and ancillary items, and not changing the tank, there is no advantage in removing the tank itself. Access to the inside of the tank is through the pump mounting hole only, so unless the tank is to be changed, do the repairs with it in the car. To remove the tank, the closing plate must be removed from the bottom of the frame and the tank pushed out from the top. To accomplish this, the bottom coolant pipes must be disconnected and moved out of the way.
Replace the pump and associated bits with the DMC Fuel Pump/Sender Module, it replaces all the items that are prone to deterioration and is a modern replacement for the other original, trouble-prone internal tank components. It also includes a new, integrated fuel sender that is far more accurate than the original or the stand-alone replacement.
