Loss of Fuel Flow
I
CAUTION
I
If normal engine operation and fuel flow is not
immediately re-established, or if the engine quits,
the electric fuel pump should be turned off. The
lack of fuel flow indication could indicate a leak
in the fuel system, or fuel exhaustion. Land at the
nearest suitable airport as soon as possible and
have the cause investigated.
If caused by fuel depletion in one tank:
FUEL PUMP Switch .............................................................................. ON
FUEL Selector ................................ SELECT OTHER TANK (FULLEST)
FUEL PUMP Switch ............................................................................ OFF
If
caused by engine driven fuel pump fai.lure:
THROTTLE ................................................................................... CLOSE
FUEL PUMP Switch ............................................................................ ON
THROTTLE .............................................. RE-ESTABLISH (as required)
MIXTURE ................................................. RE-ESTABLISH (as required)
The most probable cause of loss of fuel flow is either fuel depletion in
the fuel tank selected or failure of the engine driven fuel pump. If loss of fuel
flow occurs, turn ON the electric fuel pump and check that the fuel selector
is on a tank containing usable fuel. After power is regained, turn the electric
fuel pump OFF.
If loss of fuel flow is due to failure of the engine driven fuel pump turn
ON the electric fuel pump as it will supply sufficient fuel flow to run the
engine.
