FUEL FLOW TEST

TM 9-2320-364-20-1

Fuel is very flammable and can explode easily. To avoid serious injury or death, keep fuel away from

open fire and keep fire extinguisher within easy reach when working with fuel. Do not work on fuel

system when engine is hot. Fuel can be ignited by hot engine.

Allow engine to cool before performing troubleshooting maintenance. If necessary use insulated pads

and gloves. Hot engine components will burn and cause injury to personnel.

Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry or tools contact positive electrical

circuits, a direct short may result. Damage to equipment, injury or death to personnel may occur.
