Fuel tank - cleaning and repair
Warning: A fuel tank must be repaired professionally. On no account attempt to weld or solder a fuel tank yourself as this will result in an explosion.
1 Remove the fuel tank from the vehicle.
2 If the tank contains sediment or water, it may be cleaned out using two or three rinses with paraffin. Shake vigorously using several changes of paraffin, but before doing so remove the sender unit. Allow the tank to drain thoroughly.
3 If removal of the tank was carried out in order to mend a leak, have it repaired professionally; radiator repairers will usually do this. To remove all trace of vapour requires several hours of steaming out.
