Fuel Routing - Without Fuel Management Board
Fuel Filters & Water Separators
Fuel filters and water separators should be inspected peri-
odically for debris and replaced according to the guidelines
and instructions detailed in your engine manual, generator
(option) manual and in the filter literature.
Fuel Fill Locations
Fuel fill receptacles are located on each side of the aft deck
and are marked either “Diesel” or “GAS”. If you experi-
ence difficulty filling a fuel tank, check to see that the fuel
fill and vent lines are free of obstructions and kinks.
Anti-siphon Valves
If your yacht is gas powered, it may be equipped with anti-siphon valves. Anti-siphon valves are an integral part of
the gas fuel line barb fitting on each fuel tank. The anti-siphon valves are spring loaded and are opened by fuel pump
vacuum. In the unlikely event of a fuel line rupturing, the valve would prevent fuel from siphoning from the tank.

FIRE & EXPLOSION HAZARDS! 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 an emergency, NEVER operate the engines without the anti-siphon valve.
