FA%&URE
An engine driven fuel puinp failure is probable when the engine will only
operate
with
the boost pump on. Operation of the engine with a failed engine
driven fuel pump and
the
BOOST
ON
will require smooth uperatiat?
of
the
en-
gine controls and corresponding mixture change when the throttle is reposi-
tioned or the engine speed is changed. When retarding throttle or reducing
engine speed lean the mixture
lo
prevent the engine frorn quitting from an
overrich condition. Enrich the mixture when opening the throttle or increas-
ing engine speed
to
prevent engine stoppage frorn
a
lean condition. Always
lean to obtain a
smooth running engine. The following procedure should be
followed when a failed engine driven fuel pump is suspected:
