Fuel System
automatic shuto valve in the marina fuel pump
nozzle will stop the ow before fuel can be ejected
into the vent system when the tank is full. You
should never attempt to “top o” the tank after
the pump nozzle shuto valve has activated. This
could force fuel into the vent system and damage
emission control components.
The fuel ll is opened by pressing the release
button on the side of the cap. After fueling, make
sure to close and latch the cap. Be sure to use the
proper type and grade of fuel. Refer to the engine
owner’s manual for additional information.
DO NOT CONFUSE FUEL FILL DECK PLATE WITH THE WATER
OR WASTE FILL DECK PLATES. THESE PLATES ARE ALSO
LABELED ACCORDINGLY. IF GASOLINE IS ACCIDENTALLY
PUMPED INTO THE WATER OR WASTE TANK, DO NOT ATTEMPT
TO PUMP IT OUT YOURSELF. WATER AND WASTE PUMPS ARE
NOT DESIGNED TO PUMP FUEL AND A FIRE OR EXPLOSION
COULD RESULT. CONTACT YOUR DEALER OR THE BLACKFIN
CUSTOMER SERVICE DEPARTMENT FOR ASSISTANCE IN
HAVING THE FUEL PROFESSIONALLY REMOVED.
Fuel Tank Vents
In order to comply with U.S. EPA regulations,
the fuel tank is equipped with a special vent
located on the hull side and vent system emission
control components. A carbon lled canister in
the vent hose between the fuel tank and the vent
absorbs fuel vapors before they can escape to the
atmosphere and returns them to the fuel tank.
Carbon canisters can be damaged if they are re-
peatedly exposed to liquid fuel. Special valves in
the vent system and the automatic shuto valve
on marina fuel pump nozzles prevent the tank
from being overlled and forcing fuel into the vent
system. You should never attempt to “top o” the
tank after the pump nozzle shuto has activated.
This could force fuel into the vent system that can
damage the carbon canister or other components.
5.2 Engine Fuel Delivery System
The fuel system has one fuel tank located in the
center of the bilge below the cockpit sole. The
tank is equipped with one fuel withdrawal tube.
The fuel withdrawal tube is equipped with an anti-
siphon valve where the fuel line attaches to the
tank. This valve prevents gasoline from siphoning
out of the fuel tank should a line rupture.
Typical Engine Fuel Filter In Aft Systems Compartment
DO NOT REMOVE THE ANTI-SIPHON VALVE FROM THE
SYSTEM. SHOULD THE VALVE BECOME CLOGGED, CLEAN
AND REINSTALL OR REPLACE.
Some engines are equipped with only a water
separating fuel lter mounted on the engine.
Others have an engine mounted lter and a wa-
ter separating lter mounted in the aft systems
compartment bilge. This lter is accessed by
opening the rear hatch in the cockpit sole. All
lters should be serviced frequently to assure an
adequate supply of clean, dry fuel to the engine.
It is recommended that the lters are inspected
periodically and the elements changed as needed.
There is a primer bulb in the fuel line in the aft
systems compartment that is used to prime the
fuel system after service or as required. See
Fuel System Maintenance and the engine owner’s
manual for additional information on the fuel lters
and the outboard engine fuel system.
