d. Cleaning and Inspection. Wash the fuel tank with cleaning solvent and drain all sediment and foreign matter.
Clean the fuel tank with live steam and dry it thoroughly with clean compressed air. Inspect the tank for holes, cracks, and
dents. Check all mounting nuts for corroded or damaged threads. Clean the fuel tank straps with cleaning solvent and
blow off all fuel lines and pipe nipples with clean compressed air. Inspect all threaded surfaces. Clean rust and corrosion
from them with a stiff wire brush.
e. Repair. Weld minor holes and cracks in the fuel tank. Always fill the fuel tank with water before welding. Avoid
excessive heat while welding or soldering because it may cause warpage or distortion of the fuel tank. Clean the welds
when completed and drain the water from the fuel tank. Clean the tank with live steam and dry it with clean compressed
air. Replace all damaged or worn pipe nipples, reducer bushings, elbows, valves, and mounting nuts. Use a softfaced
hammer to straighten out bent or twisted fuel tank straps. Replace the straps if broken or cracked. Replace the fuel
strainer if the screen mesh is torn, corroded, or splitting. Clean the screen mesh with compressed air. Check the fuel tank
cap for tightness and replace if it is worn or cracked, or if the locking lugs are broken off.
