6.3.4 Fuel Distribution System
The fuel is delivered from the tank to the engine through the “Integrated Fuel Demand Valve” (IFDV),
anti-siphon valve, and the fuel line. The IFDV prevents built up pressure inside the tank from being
transferred to the engine, while still allowing fuel to flow to the engine 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. Some fuel would still leak from the line, but the valve will
not allow the entire contents of the tank to siphon into the boat.
6.3.5 Filling Fuel Tanks
The fuel system is designed to automatically shut off the fuel nozzle when the tank is full via 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.
What does the IFDV do?
The integrated fuel demand valve, used in conjunction with integrated fuel systems, is for
below-deck use, eliminates pressurized fuel from reaching fuel distribution lines / the engine, and
ensures that fuel is provided to the engine on demand rather than as a result of pressure in the tank.
Additional features include:
• Compatible with Ethanol-blended fuels
• Eliminates the need for rigid fuel distribution lines in
pressure relief systems (per ABYC H-24, 15.9)
• 2-year warranty
!!! WARNING
The use of a portable fuel tank to fill your fuel tanks can result in overfilling and circumvent the safe
features designed into our fuel tank system.
!!! WARNING
Modification of any of the fuel system components or the replacement of these components with
unauthorized parts may result in over-pressurization of the fuel system and circumvent the safety
features designed into your fuel system.
