2015 Carolina Cat 23CC Owners Manual
5.3 FUEL
SYSTEM
Due to the nature of the hull design, your Carolina 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.
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 annually, including those normally hidden
from view. Tighten all connections, replace deteriorated hoses, clamps or fittings, and inspect the fuel/water
separators during this check. Carolina Cat has provided inspection plates in the cockpit floor and along the gunwales
to assist you with annual maintenance. The inspection plates along the gunwales are located below the fuel fill port
inside the cockpit.
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 system
repairs and engine maintenance should be performed by a qualitifed marine technician.
The fuel/water separators are installed between the tank pickup and the engine. They are located in the aft rigging
space on the inboard side of the walk-thru bulkhead. These can be reached through the inspection hatch located at the
transom walk through area. Inspect these filters regularly and replace when needed.

5.3.2
Fuel Tank
Your boat is equipped with a Low Permeation Crosslink Polyethylene fuel tank with a fuel capacity of 46.5 gallons
per tank. The useable capacity of the fuel tank is different from the tank capacity marked on the tank from the
manufacturer. The difference is the ullage area that has been incorporated into your tank. It is recommended that you
follow all the instructions regarding the filling of fuel tanks.
5.3.3
Fuel Vent
The fuel tank vent is integrated into the fuel fill deck fitting (See fig. 5.3.6) The vent serves as an over
pressure/vacuum release with anti-surge and flame/spark arresting protection. The fuel vent system also plays an
important role in controlling the “FULL” level of fuel with the use of FLVV (Fill Limit Vent Valve). Grade Valves
have been added to the tank which allows proper ventilation of the tank when the boat is stored, or trailered, on a
moderate incline, without fuel. Note all ways inspect to insure the fuel fill deck fitting is free of debris and in proper
working condition.
