2-50. STORAGE MAINTENANCE PROCEDURES (CONT).
Fuel system extended storage.
Drain fuel tank (Para 4-8).
Change all fuel filters (Para 4-3, 4-13, 4-15, 4-17).
Ensure the fuel tank contains at least 20 gallons (75.7L) of treated fuel. The fuel should be treated
with Biobor JF (Item 24, Appendix C), (or equivalent). The addition of 3 teaspoons of Biobor to 20
gallons of fuel will provide adequate protection against fungus growth. When storing a vehicle in
freezing conditions, the addition of 3 ounces (88.7 ml) of isopropyl alcohol (Item 17, Appendix C),
to 20 gallons of diesel fuel will help prevent fuel line freeze up.
Run engine 5 minutes to circulate clean treated fuel throughout the fuel system.
All fuel that is added to the vehicle during storage must be treated. While in storage, there must
always be at least 20 gallons (75.7L) of treated fuel in the vehicles fuel tank.
Cap off fuel system.
Battery extended storage.
Remove batteries from vehicle (Para 7-88) and keep fully charged (TM 9-6150-200-14).
Check the coolant level (TM 9-2320-364-10). Test the coolant to ensure that the cooling system is
protected against corrosion and temperatures down to 30 degrees F (34 degrees C). Add antifreeze or
corrosion inhibitors compatible with ethylene glycol base antifreeze if cooling system is not adequately
protected (TB 750-651).
When removing vehicle from storage, perform the following tasks:
Install batteries (Para 7-88).
Conduct a visual inspection to the vehicle and remove moisture proof tape from engine, transmission,
transfer case and fuel system. Check lubricant levels and tire pressures. Correct any discrepancies.
Lubricate the chassis, ancillary equipment, and oil can points (Para 2-9 and TM 9-2320-364-10).
