  Q: How to remove and install the fuel tank from a coupe, sedan, or station wagon on Mercedes-Benz 300TD?

  A:

  Take the cable out of the negative battery post and empty the tank by pouring fuel out at the bottom with the plug. In case of coupe and sedan cars, hose clamps in the fuel suction and return hose should be loosened, pulled off and the holes inserted. This is followed by pulling out the trunk floor mat, trim panel and then unscrewing the retaining screws to take away the trunk rear wall panel to access the fuel tank. Unscrew the nuts holding the retention tank, complete the unplugging of the electrical connector, and remove the fuel tank out of the trunk keeping the vent line intact. In station wagon models eliminate trunk floor and middle shelf paneling and wipe away fuel gauge sender and hose opening covers. Disconnect the hoses and loosen the screwdriver-clamps of the sender connector. Elsewhere, underneath the car, loosen the clamps and unscrew and reinsert the fuel hose and the fuel return line with an appropriate container underneath, to collect any leftover petrol. Take out the retaining bolts and take down the fuel tank of the car. Installation is the opposite of un-install. Caution Never carry out any repair work, heat or flame, on the tank but should have been emptied of fuel and vapor, and should never attempt any repair without a skilled man.

  Q: What precautions should be taken when repairing or removing a fuel tank to prevent ignition of explosive fumes on Mercedes-Benz 300TD?

  A:

  Repairs on the fuel tank or filler neck should be done by a qualified expert who can perform this sensitive and hazardous task since explosive fumes may exist even after cleaning and flushing the fuel system, and this may certainly be ignited during the repair. When the fuel tank is taken out of the car, one should not leave it anywhere, where it might come in contact with sparks or open flames to ignite the fumes, especially in a garage that has a natural gas-type device, the pilot light may cause an explosion.
