2015 World Cat 320CC Owners Manual
The fuel is delivered from the tank to the engine through the “Interated Fuel Demand Valve” (IFDV), anti-siphon
valve, and the fuel line. The IFDV prevents the built up pressure inside the tank from being transferred to the engine
while still allowing fuel to flow as the engine requires it for operation. The anti-siphon valve is a safety feature
designed to prevent the fuel from siphoning out of the tank if the fuel line were to be cut or broken below the level of
the fuel in the tank. In this case, some fuel would leak from the line, but would not allow the entire contents of the
tank to siphon into the boat. (See fig 6.3.6)
6.3.5 Filling Fuel Tanks
The fuel system is desinged to automatically shut off the fuel nozzle when the tank is full by the “Inlet Control
Valve” (See Fig 6.3.6) similar to an automotive fuel system. The tank is filled when the fuel fill nozzle has shut itself
off the second time. Attempting to fill the tank past this point may cause some of the components to not function
properly, or malfunction.
