3100 OFFSHORE

DO NOT CONFUSE FUEL FILL DECK PLATES WITH THE WATER OR WASTE FILL DECK

PLATES. THESE PLATES ALSO ARE LABELED ACCORDINGLY. IF GASOLINE OR DIE-

SEL FUEL IS ACCIDENTALLY PUMPED INTO THE WATER OR WASTE TANK, DO NOT

ATTEMPT TO PUMP IT OUT YOURSELF. WATER AND WASTE PUMPS ARE NOT DE-

SIGNED TO PUMP FUEL AND A FIRE OR EXPLOSION COULD RESULT. HAVE THE FUEL

PROFESSIONALLY REMOVED AND THE COMPONENTS OF THE FRESH WATER SYSTEM

REPLACED AS NECESSARY.

Fuel Vents

There are two fuel vent fittings, one on each side of the hull. While the tank is being filled, the air displaced

by the fuel escapes through the vent.

After fueling, replace the fill cap(s), and wash the areas around the fuel fill plates and below the fuel vent(s).

Residual fuel left on the deck and hull sides can be dangerous and will yellow the fiberglass or damage the

striping.

3.2 Gasoline Engine Fuel System

The fuel system on the Pursuit 3100 Offshore has two fuel tanks and two manual fuel valves. The port tank

fills from the port gunnel and the starboard tank fills from the starboard gunnel.

There is one “ON/OFF” valve for each engine fuel line. The fuel valves are located on the fuel tanks. The

valves are off when the handle is perpendicular to the fuel flow. They should always be turned off before

servicing the fuel filters or any other component of the fuel system.

The starboard engine is supplied by the starboard fuel tank and the port engine is supplied by the port fuel

tank. There are no valves that allow the selection of the fuel tanks. This is because some engines with fuel

injection circulate much more fuel than they consume to cool the fuel and reduce the possibility of a vapor

lock. Some fuel injected gasoline engines return the unburned fuel to the fuel tanks, while other fuel injected

engines return the fuel to a vapor separating tank on the engine. If the unburned fuel is returned to the fuel

tanks, it is extremely important that it is returned to the same tank that is suppling the engine. This eliminates

the possibility of fuel being supplied by one fuel tank and returned to the other tank, a situation which could

cause one of the fuel tanks to become overfilled and fuel to flow out the fuel tank vent. Please refer to the

engine owner's manual for specific information for the fuel system used on the engines installed in your boat.

Fuel withdrawal lines are equipped with anti-siphon valves where the lines attach to the fuel tanks. These

valves prevent gasoline from siphoning out of the fuel tank should a line rupture.

DO NOT REMOVE THE ANTI-SIPHON VALVES FROM THE SYSTEM. SHOULD AN ANTI-

SIPHON VALVE BECOME CLOGGED, CLEAN AND REINSTALL OR REPLACE. IF A FUEL

LINE SHOULD LEAK, ANTI-SIPHON VALVES PREVENT A SUBSTANTIAL AMOUNT OF

FUEL FROM FLOWING INTO THE BILGE. ANTI-SIPHON VALVES ARE REQUIRED, BY

THE U.S. COAST GUARD, TO BE INSTALLED IN ALL BOATS EQUIPPED WITH GASO-

LINE ENGINES.
