We remove the fuel tank for flushing or for replacement
We prepare the vehicle for the task. It is desirable that the tank be empty.
We place the vehicle on a lift or an inspection pit.
We release the fuel pressure in the supply system and disconnect the wiring harness connector from the connector of the fuel module cover (see the article – Repair of the fuel module Renault Duster).

We also withdraw three more rivets securing the heat shield
We remove the shieldWe bring one of the parking brake cables out of the front holder on the fuel tankWith side cutters we cut the plastic clip securing the rear holder of the parking brake cableWe bring the cable out of the rear holderWe also bring out of the two holders on the tank the other parking brake cable1 - pipe connecting with the adsorber of the fuel vapour recovery system; 2 - pipe connecting with the fuel filter in the engine compartment
Under the floor of the vehicle, two pipes lead to the front part of the fuel tank, the pipe connecting with the adsorber and the fuel filter
Having pressed the retainer of the end piece (grey colour) of the fuel supply pipe to the filter, we disconnect the end piece of the pipe connecting with the union of the fuel module coverWe also disconnect the end piece of the other pipe from the pipe connecting with the fuel tankSecuring points of the fuel tank to the vehicle floor: 1 - rear securing bolts, 2 - side securing nuts, 3 - front securing boltWe install an adjustable support under the fuel tank, placing a wooden block so as not to damage the tankWith a tall 13 mm socket we unscrew two nuts of the side securing of the fuel tankWe unscrew two bolts of the rear and the bolt of the front securing of the tankWe remove the metal gasket from the flange of the tank.
We also remove the other metal gasket.
Having lowered the tank slightly on the support, we pass the parking brake cables over itWhen lowering the tank we control the separation of the filler neck from the filler pipe and of its plastic adapter in the connection with the bodyWe lower the fuel tank on the adjustable support, holding the filler pipeWe remove the tank as an assembly with the fuel module.
If necessary, we withdraw from the tank the fuel module.
We install the fuel tank in the reverse order.
Having poured fuel into the tank, we switch on the ignition and check the tightness of the connections of the fuel line.
Location of the fuel tank on the 4x2 vehicle
On the 4x2 vehicle the operations for removing the fuel tank are practically the same (only the operation for removing the propeller shaft is absent) as on the 4x4 vehicle
