METAL BODY REPAIR - OD1653 - LESSON 2/TASK 3
Before the actual repair of a tank, the vapors must be removed and the
filler neck cap replaced. After connecting the air hose to the fuel outlet
pipe connection and placing the tank in a water vat, observe the tank for
any leaks (with air pressure set at five psi). Remove the tank and shut off
the air supply. To repair the damaged area, first heat the area, clean or
wire brush and tin the area, and then solder the leak. The final step is to
retest with air to make sure the damaged area was repaired properly.
