Remove fuel manifold retainer screws and remove
retainers from fuel injectors.
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.
Install oil tank assembly. Refer to Oil Tank
Assembly on p. 187.
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.
Removal
Disconnect the battery cables at the battery.
Relieve fuel system pressure. Refer to Relieving
Fuel System Pressure on p. 166.
Remove fuel manifolds. Refer to Fuel Manifold
Service on p. 168.
