10 CHAPTER 3: COMPONENTS / SYSTEMS

Fuel System

FIRE/EXPLOSION HAZARD - The fuel system MUST be inspected thoroughly the
first time it is filled and at each subsequent filling.
Fueling instructions in the Owner's Manual and any fuel recommendations in the
engine manual must be followed (these manuals are included in the owner's packet).
Air in the diesel supply system can stop an engine or severely restrict performance. If you
suspect air in your diesel fuel lines, refer to your Engine Manual for detailed instructions on
how to "bleed" the system.
Avoid the storage or handling of gear near the fuel lines, fittings and tank.
The filters/separators should be inspected periodically for debris and replaced as needed according to the instructions
detailed in your engine manual, generator manual and in the filter literature supplied in your owner's packet.

Fuel Management Board

On models equipped with a fuel management
board, fuel can be directed from either tank
to the engines and generator using the supply
valves. The fuel management board is
located under the port engine access hatch.

Fuel Quality

Make sure your fuel suppliers are reputable
and can be relied upon to furnish clean, high
quality fuel. Once you have found such sup-
pliers, keep your tank as full as possible with
their fuel, allowing for expansion due to tem-
perature variations. Then, if you are forced to
add to the tank with a potentially poor qual-
ity supply, the portion of poor quality fuel
will be minimized.
Fuel Fills and Vents
Fuel fills are located either on the aft deck or on the side decks adjacent to the aft cockpit. Fuel receptacle caps are
marked "Diesel" or "GAS". Fuel vents are normally located in the hull or transom below and in the same general area
as the fill. If you experience difficulty filling the fuel tank, check to see that the fuel fill and vent lines are free of
obstructions and kinks.
Anti-siphon Valve (Gas Engines Only)
An anti-siphon valve is an integral part of the fuel line barb fitting on each fuel tank. These valves are spring loaded
and are opened by fuel pump vacuum. If a fuel line ruptures the valve prevents the siphoning of fuel from the tank.
FIRE/EXPLOSION HAZARD - If an engine problem is caused by fuel starvation,
check the anti-siphon valve. If the valve is stuck or clogged, shut down the engine and
replace it. Except in a crisis, NEVER operate the engines without the anti-siphon valve.
