Section II. FUEL STORAGE SYSTEMS
5-4.
General. Fuel storage systems may be enclosed metal containers or nylon fiberglass tanks. All systems are
susceptible to contamination from dirt or water. Metal tanks are susceptible to corrosion which will contaminate the
stored fuel. Draining and purging fuel tanks of contaminants is of major-importance for long usage. Leakages caused by
normal vibration or actual combat damage must be repaired before the generator can be used.
5-5.
Fuel Tank, Leaks. Fuel tank leaks are difficult to repair in a battlefield environment. The repairs are also
dictated by the type of material from which the fuel tank is manufactured. Fuel leakage is an indication that a fuel
storage container is damaged. Time required for repairs will vary with the fuel tank location and ease of access for
repairs. The area surrounding the damage must be cleaned to make a good repair.' Heat will hasten curing of fiberglass
or epoxys.
