6 Fuel tank cleaning and repair - general information
1 All repairs to the fuel tank or filler neck should be carried out by a pro-
fessional who has experience in this critical and potentially dangerous
work. Even after cleaning and flushing of the fuel system, explosive fumes
can remain and ignite during repair of the tank.
2 If the fuel tank is removed from the vehicle, it shouldn’t be placed in an
area where sparks oropen flames could ignite the fumes coming out of the
tank. Be especially careful inside garages where a natural gas-type
appliance is located, because the pilot light could cause an explosion.
