FUEL SYSTEM
FUEL COMPONENT SERVICING
Disconnect fuel manifold fittings from fuel injector
ports, then remove the manifold assemblies.
Installation
Check condition of sealing O-rings on fuel mani-
fold fittings. Lubricate O-rings with outboard lubri-
cant and insert fuel manifold fittings into injector.
Both fittings must be fully seated into the injector
fuel ports.
Install retainer and screw. Retainer must engage
the outer groove of the manifold fittings.
Install the fuel manifolds to the fuel pump assem-
bly and secure with clamps:
•
Fuel supply manifold to circulation pump.
•
Fuel return manifold to vapor separator.
Fuel Injector Service
Mark fuel injectors to show cylinder locations.
IMPORTANT:
Fuel injectors must be installed in
the correct cylinder locations. Use
Evinrude Diag-
nostics
Software to make sure that
EMM
program-
ming matches injector positioning. The
Injector
Coefficients
screen displays injector serial num-
bers.
Use caution when handling fuel injectors. Prevent
dirt and debris from entering fuel inlet and outlet
ports of injectors or fuel manifolds. Cover the
injector nozzle port in cylinder head to prevent
contamination of combustion chamber.
