The next step is used in AWD vehicles, and it is noteworthy that whenever the battery is unplugged, a number of the systems have to be re-learned before they are able to work correctly. The first step involves removing the cable of the negative battery terminal. In order to gain access to the fuel transfer pump and fuel level sender check hole cover, one must remove the rear seat cushion, recline the carpeting, and remove the cover of the access holes. Then, loosen the electrical connector and take the lock ring off the inspection cover: special tools are sold at most auto parts stores, and it can be done with a pair of pliers; locking one end of the lock ring to one of the tank tabs and the other to another, and turning the pliers slowly to turn the ring counterclockwise. This procedure is advised to drain the gas in the tank. To disconnect the fuel level sender harness connector located inside the
Fuel Tank, reach inside and find the connector and press the tabs which release the connector connector out of his bracket pushing it through. To disassemble the fuel level sender, press the two tabs at the top and slide the sender upwards retaining the arm. Installation is the opposite of removal, whereby the connector of the harness of the sender is embedded into the bracket and then the vehicle harness reconnected. This is because the fuel tank has a transfer pump which cannot be serviced individually and in case of fault, the fuel tank should be replaced as a whole.
