2-10. OPERATION IN EXTREME COLD.
The Forward Area Refueling Equipment will operate satisfactorily in extreme cold weather. Use proper precautions
when handling fuel. Protect hose connections and nozzles from ice and snow. Inspect sight gage more frequently
for moisture. The low temperature operational limit is –25°F (–32°C).
2-11. OPERATION IN EXTREME HEAT.
The Forward Area Refueling Equipment will operate in extreme heat. The high temperature limit is 125°F (52°C).
A hose full of fuel and closed at both ends must not be exposed to the sun for ex-
tended periods. Expansion of the fuel will damage the hose. Open vent valve on
fuel separator when not in use.
2-12. OPERATION IN DUSTY OR SANDY AREAS.
The Forward Area Refueling Equipment is affected by dusty or sandy conditions. The gravity fill adapter spouts
should be cleaned immediately before refueling operations start. Keep all dust caps in place except when in use.
Refer to TM 5-4320-313-14 for operation of the pumping assembly.
2–13. OPERATION UNDER RAINY OR HUMID CONDITIONS.
Keep gravity fill adapter capped except when in use. Dry nozzles thoroughly before refueling aircraft.
2–14. OPERATION IN SALT WATER AREAS.
Operation in saltwater areas presents corrosion problems. Keep exposed metal parts clean by washing with fresh
water and drying thoroughly.
2–15. OPERATION IN HIGH ALTITUDES.
Pump output may fall off slightly due to lower horsepower output of the engine at high altitudes.
