INBOARD FUEL TANKS.
INSPECTION AND REPAIR OF ALUMINUM FUEL TANKS (INBOARD).
Fuel tanks should be completely drained before inspection. (Refer to Draining Fuel Systems. Chapter
12.) Each tank should be carefully inspected forsignsof leaksasindicated by telltale stains. Intheeent a fuel
leak is detected. the fuel tank must be removed, and repaired as follows:
I. The tanks should be sloshed in accordance with instructions provided on each can of Randolph
Sloshing Sealer 802. (M IL-L-6047B). Piper P N 757 572. One gallon of sealer is required for each tank. When
sloshing. the finger strainer. fuel sender unit. sight gauge and drain valves must be removed before proceeding
Seal all openings. After sloshing. check for leaks using a water and soap solution and apply 1.5 pounds of air
pressure.
2. If the tank being inspected has previously been sloshed, the interior of the tank should be inspected
for signs of peeling or chipping sealer. Particular attention should be given the area around the filler neck as a
result of the metal nozzle of the gas filler hose nicking the sealer. This inspection can best be accomplished
using a mirror and inspection light through the filler neck. If peeling and or chipping has occurred and
separated material is found. the tank should be sloshed as explained in Step 1.
3. After sloshing. reinspect as outlined in Step 2 at intervals of 100 hours.
- NOTE-
Thefuel tank should be replacedif it has been damaged to the extent
it cannot be repaired by above procedures.
Seal all pipe threads with medium weight "Tite Seal" gasket and
joint sealing compound. (Refer to Chart 9105for manufacturer.) To
prevent sealant from entering fuel system, do not apply to first two
threads.
