Fuel System - World Cat 2009 boat Owner's Manual

World Cat

FUEL SYSTEM

Due to the nature of the hull design, each World Cat is equipped with a port and starboard fuel system. These sys-
tems 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, com-
prehensive checks of hoses and fittings should be completed at least annually, including those normally hidden from
view. Tighten all connections, replace deteriorated hoses, clamps or fittings, and replace the fuel/water separators dur-
ing 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 bol-
sters 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 connect 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 sys-
tem repairs and engine maintenance should be performed by a qualified marine technician.
SENDING UNIT
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.
