FUEL FLOW THROUGH FILTER
Check flow of fuel through fuel filter
(a) If fuel flows freely without air, go to
Step 3 of this fault.
(b) If air in fuel lines, check for air
leaks, shut down engine
(TM 10-3930-673-10) and bleed
system (Para 5-11).
LINE TO FUEL

operating engine with known clean fuel
from temporary supply tank.
(a) Disconnect fuel line at fuel/water
separator, where line leads to fuel
(b) Place disconnected end of fuel line
in temp tank of known clean fuel.
(c) Start engine and run it for
approximately 5 minutes to
determine if engine performance
improves with known clean fuel.
(2) If fuel in fuel tank proves clean, use as
LINES O FUEL/WATER
