FUEL SYSTEM
COMPONENTS
8
Fuel Manifolds
The fuel supply and return manifolds route fuel
through the high pressure side of the fuel system.
Fuel Supply Manifold
The fuel supply manifold supplies pressurized fuel
to the inlet port of each fuel injector.
Fuel Return Manifold
The fuel return manifold provides a route for fuel
passing through the fuel injectors to flow back to
the fuel chamber of the vapor separator.
Fuel Injectors
Fuel injectors are fuel metering, electric solenoids
(55 V) bolted directly to the cylinder head. The
EMM
controls the activation of each injector by
rapidly connecting and disconnecting the injec-
tor’s internal coil to ground.
Fuel Flow Compensation
The flow rate of each injector is measured as part
of the manufacturing process. This information is
recorded and assigned to the injector by serial
number.
The
EMM
is programmed to compensate for vari-
ations in fuel flow. Each injector and its location on
the outboard is identified by the
EMM
. DO NOT
install an injector without updating the compensa-
tion software.
Each service injector includes its fuel flow infor-
mation on a 3.5 in. floppy disk. This software
allows the
EMM
to be reprogrammed for this injec-
tor’s unique fuel flow characteristics.
IMPORTANT:
The cylinder location of each
injector must always be maintained.
EMM
pro-
gramming is associated with the cylinder location
of each injector.
Injector Fuel Supply
Fuel is supplied to the injectors by the fuel circula-
tion pump and the fuel supply manifold.
Each injector has internal fuel passages. These
passages are designed to:
•
Provide fuel to the injector's injection chamber
•
Route fuel through the injector housing to cool
the injector coil and armature.
