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 but-
ton 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 overlled 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.

The fuel system has one fuel tank located in the
center of the bilge below the cockpit sole. The
tank is equipped with two fuel withdrawal tubes.
Each fuel withdrawal line is equipped with an anti-
siphon valve where the line attaches to the fuel
tank. This valve prevents gasoline from siphoning
out of the fuel tank should a line rupture.

DO NOT REMOVE THE ANTI-SIPHON VALVES FROM THE
SYSTEM. SHOULD THE VALVE BECOME CLOGGED, CLEAN
AND REINSTALL OR REPLACE.
A fuel lter for each engine is installed in the
aft systems compartment bilge and/or on the
engines. They are the water separator type and
should be serviced frequently to assure an ad-
equate supply of clean, dry fuel to the engines.
It is recommended that the lters are inspected
periodically and the elements changed as needed.
Filters mounted in the aft systems compartment
are accessed by opening the rear hatch in the
cockpit sole. There is a primer bulb in the fuel line
near each fuel lter that is used to prime the fuel
system after service or as required. See Fuel Sys-
tem Maintenance and the engine owner’s manual
for additional information on the fuel lters and
the outboard engine fuel system.
