  Q: How to remove and refit the fuel tank on Mercedes-Benz 190E?

  A:

  To remove the fuel tank, always, first empty the tank by draining the remains through the filler neck using a siphon or hand pump upon normal use. Always park on a flat level area, chock the front wheels and hold the rear raised up on axle stands. Unscrew the battery negative terminal and leave it off the terminal. Removing all the hoses disconnect the fuel supply and return and vent hose and keep all the hoses labeled to be refitted later and plug in the open ends to stop leakage and dirt infiltration. The large rubber closing grommet attached to the ports of the fuel tank in the luggage compartment should be removed, the retaining clips, the carpet, and the fuel tank cover panel then released. Disconnect the wiring of the fuel gauge sender unit and loosen it out of the clips. Unscrew the fuel tank fixing nuts and access the drain hose by lifting the tank slightly and pulling out the drain hose taking note of how it is run, then unscrew the filler neck of the bodywork and retrieve sealing ring(s) and sleeves. Lift the tank to the clear, drag it back and take it out of the luggage space re-gathering any loose pieces of padding. Take out the fuel strainer in the tank unscrewing the O-ring seal of the tank and wipe out the sediment in the tank with clean fuel and again screw the fuel strainer with another O-ring seal. In case the tank has been contaminated, take out the gauge sender unit, swill it with clean fuel and in case it is very corroded or leaking repair it or replace it. Reverse the removal procedure in order to attach it again, so that all fixings are tightened to the necessary torque, padding strips are correctly laid in place, the drain hose is laid correctly and the wiring plug of the sender unit is firmly reconnected. Lastly, take the vehicle on the road and investigate fuel leakage concerning all the components that were disturbed.
