  Q: What steps should be taken before removing a fuel tank to ensure safety and proper handling on Volvo V40?

  A:

  Before removing the tank, it must be drained of as much fuel as possible to avoid dangers associated with fuel handling and storage, ideally leaving it almost empty. Any remaining fuel can be drained using a hand-pump or siphon through the filler neck, or by jacking up the rear of the car and placing a large-capacity container under the fuel filter. Clean the fuel inlet quick-release coupling on the filter, disconnect it while being prepared for an initial release of fuel under pressure, and allow the fuel to drain into the container, removing the fuel filler cap to improve flow. Disconnect the battery negative lead, the filler pipe, and breather hose from the fuel tank, as well as the fuel supply and return pipes from the fuel filter cartridge. Remove the securing screws and detach the heat shields from the front of the tank, then position a trolley jack under the center of the tank with a protective wooden pad, raising it just enough to take the weight. Undo the nuts to release the front edges of the tank retaining straps, lower the jack slightly, disconnect the vent hoses, and detach the wiring harness from the top of the tank before lowering and removing the tank from under the car. If the tank is contaminated, remove the gauge sender unit and fuel pump, disconnect the ventilation hoses and filler tube, and swill the tank out with clean fuel. If a new tank is to be fitted, transfer all components from the old tank, renewing the filler tube seal and securing nut. For refitting, locate the tank in position, tighten the rear strap mountings, center the fuel pump plastic nut, lubricate the filler neck seals, and ensure proper placement of the drain tube. Finally, refill the tank with fuel and check for any signs of leakage before driving.
