World Class Catamarans
3-2
FUEL SYSTEM
Due to the nature of the hull design, each World Cat is equipped with a port and starboard
fuel system. These systems act independently, providing fuel to the engine on their respective
side. Tanks are constructed of polyethylene material to prevent corrosion, and feature dual hull
side vents to avoid over-pressurization of the system. This helps eliminate “blow back” and its
damaging effects on your gelcoat.
Hoses are NMMA certified, and fittings are clamped securely to reduce the potential for
leaks. However, comprehensive checks of hoses and fittings should be completed at least annu-
ally, including those normally hidden from view. Tighten all connections, replace deteriorated
hoses, clamps or fittings, and replace the fuel/water separators during this check. World Class
has provided inspection plates in the cockpit floor and along the gunwales to assist you with
annual maintenance. To access the inspection ports along the gunwale, you will need to remove
the cockpit bolsters by removing the screws that hold it in place. To access the screws, pull up
gently on the bottom of the bolster and locate the drain grommets. The factory installs screws in
every other grommet to secure the bolster. Remove these and pull up and out on the cushion to
remove.
If you experience fuel flow problems, remove the fuel feed hose from your engine and con-
nect it to a portable fuel tank. Doing so will help you determine if your fuel system or the engine
is the source of the problem. Fuel system repairs and engine maintenance should be performed
by a qualified marine technician.
The fuel/water separators are installed between the tank pickup and the engine. They are
located in the aft rigging space on all models except the 270 SD, 270 TE, and 330 TE. On those
models, they are mounted on the hullside and can be reached through access doors on the
cockpit walls. Inspect these filters regularly and replace when needed.
