Cleaning and inspection. Remove the electric fuel pump 7. To remove dirt and deposits, rinse the tank with gasoline. Then rinse and steam the tank from gasoline residues with a stream of hot water.
Carefully inspect the fuel tank along the joint line; the weld should be uniform and continuous, without cracks or unwelded areas.
Check the tank for leaks by supplying air under pressure of 0.02-0.03 MPa (0.15-0.25 kgf/cm²) in a water bath for 50 seconds, if necessary, solder the leak with soft solder.
Warning: Only a well-cleaned fuel tank that does not contain gasoline vapors, which may ignite during soldering, may be soldered.
