CXO300 OWNER’S MANUAL
6.4.8 INSPECTING FUEL SYSTEM
Your installation includes 2 fuel filters per outboard, one filter on the outboard itself and one filter-water
separator unit on your vessel. It is important to regularly inspect and drain any water collected in the
separator. Inspect the filter housing for leaks. Do not disturb the fuel filters themselves.
 NOTE
The outboard-mounted filter is included as protection from contaminants entering the common-rail
system when the outboard and vessel fuel supply are disconnected. The vessel-side filter is primary
during normal operation.
To inspect the fuel system
1 Check all visible sections of fuel hose for cracking or evidence of fuel leakage, especially at their ends
and under clamps.
2 Check all fuel line clamps for tightness and correct seating; clamps should sit perpendicular to the
direction of hose run and should be located over a section of hose seated on a spigot (hose barb), so
that the hose is effectively clamped to the spigot.
3 Check that the bolts securing the filter heads on the outboard and on your vessel are tight and held
against the respective mounting brackets.
4 Check that the vessel filter is screwed tightly into the filter head and that there is no evidence of fuel
leakage around the threads underneath the filter head.
5 Visually inspect the outboard filter for any leaks around the canister or filter head. Do not physically
disturb this filter.
6 Check that the hose fittings (hose barbs) are tight inside the filter heads.
7 Check that all filter drain ports are closed tight.
