(3) Unscrew the fitting nut and disconnect the fuel line which joins the carburetor with the close nipple (12).
(4) Remove the nuts (16) and lockwashers (17) attaching the fuel tank straps (15) to the fuel tank (6).
(5) Bend the fuel tank straps (15) away from the fuel tank (6). Remove the fuel tank.
c. Disassembly.
(1) Place the fuel tank on a workbench and make sure that there is no open flame in the vicinity. Unscrew and
remove the close nipple (12) from the tee connector (11).
(2) Unscrew the fitting nuts and remove the fuel line (13).
(3) Unscrew and remove the close nipples (12) and tee connector (11).
(4) Remove the fuel tank valves (10).
(5) Use a pipe wrench to remove the pipe nipple (7) and both elbows (9).
(6) Remove the reducing bushings (8).
(7) Remove the pipe nipples (7) from the fuel tank (6).
(8) Twist the fuel strainer (5) counterclockwise and remove it from the filler neck of the fuel tank (6).
(9) Unscrew and remove five screws (1) and lockwashers (2) attaching the fuel gage transmitter (3) to the fuel
tank (6).
(10) Tap the fuel gage transmitter (3) lightly with the wooden handle of a screwdriver to loosen it from the fuel
tank body. Lift up the transmitter, being careful not to damage or bend the float lever. Remove the
transmitter gasket (18).
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.
