Fuel Systems
3.1 General
The fuel system of your boat is designed
to meet the requirements of the U.S. Coast
Guard, Environmental Protection Agency
(EPA), National Marine Manufacturers Asso-
ciation (NMMA), and American Boat and
Yacht Council (ABYC) in effect at the time of
manufacture.
DANGER
!
FIRE/EXPLOSION HAZARD
Fuel and its vapors are highly explo-
sive when exposed to open flame or
spark, resulting in death or serious
injury.
• Make sure no vapors are present
before turning on electrical equip-
ment or starting engines.
• Make sure fuel is added to the
fuel tank only. DO NOT confuse
other deck fills with fuel fills.
• DO NOT remove anti-siphon
valves from the system.
• Turn off all electrical switches
before servicing the fuel system.
• DO NOT drain any fuel into the
bilge.
• Check all fuel lines and fittings for
leaks before and after starting the
engines and after any fuel system
service.
• Prime the fuel system and check
all fittings for leaks before and
after starting the engines.
• DO NOT block fuel vents.
• DO NOT store fuel in any contain-
ers or compartments not desig -
nated for fuel storage.
Tiara has engineered an improved, EPA-com-
pliant fuel tank fill and vent system. The sys -
tem reduces or eliminates fuel spillage when
using a standard automatic shut-off fuel fill
nozzle at marinas and gas stations. While
this system provides a clean, consistent refu-
eling experience, it still requires the opera-
tor’s attention and must not be defeated by
attempts to over-fill the tank with fuel. This
system will automatically provide the proper
air space (approximately 5% of total tank vol-
ume) in the fuel tank to accommodate the
expansion of fuel during daily temperature
cycles.
The fuel cap has been updated to help the
operator verify the cap is properly closed.
This fuel system is engineered to vent
through a carbon canister when the fuel
cap is installed. This will greatly reduce fuel
vapors that escape into the atmosphere and
reduce the fuel odor that can be present with
traditional systems.
The fuel system was factory-inspected and
pressure-tested in accordance with regu-
lations in effect at the time of manufacture.
It is the responsibility of the boat owner to
maintain the safe condition of the system.
Inspect the system frequently to ensure no
deterioration or loosening of connections has
occurred.
NOTICE
!
Certain bulkhead areas are sealed in
compliance with U.S. Coast Guard
regulations at the date of manufac
-
ture. Any modifications must be made
in accordance with the regulations.
3.2 Fuel System
WARNING
!
Failure to follow proper fuel system
priming procedures will result in dam
-
age to fuel management system. The
fuel system should be serviced by
qualified personnel only. In the event of
absolute fuel depletion to the engines,
contact a certified Mercury Marine
technician.
