Removal
Disconnect the battery cables at the battery.
Relieve fuel system pressure. Refer to Relieving
Fuel System Pressure on p. 189.
IMPORTANT: Note the locations and position-
ing of all spark plug leads and retainer clips prior
to disassembly.
Remove clamps and disconnect the fuel mani-
folds as follows:
• Fuel supply manifold to circulation pump
• Fuel return manifold to vapor separator
Remove fuel manifold retainer screw and remove
retainer from fuel injector.
Disconnect fuel manifold fittings from fuel injector
ports, then remove the manifold assembly(s).
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.
Reconnect spark plug leads and battery cables.
Start outboard briefly to pressurize fuel system.
Turn outboard OFF and inspect all fuel system
components for leaks.
Install lower engine covers and air silencer.
