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

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

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

TEMPT TO PUMP IT OUT YOURSELF. WATER AND WASTE PUMPS ARE NOT DESIGNED

TO PUMP FUEL AND FIRE OR EXPLOSION COULD RESULT. HAVE THE FUEL PROFES-

SIONALLY REMOVED AND THE COMPONENTS OF THE FRESH WATER SYSTEM RE-

PLACED AS NECESSARY.

FUEL VENTS

There are two fuel vent fittings for the gasoline fuel tanks, 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 Fuel System

The outboard fuel system on the Pursuit SF 345 has two fuel tanks and two selector valves. Refer to the

Schematics section of this manual. The fuel valves are located in the aft starboard compartment of the cockpit.

The valves are identified as starboard and port engine. Either the aft tank or the forward tank can be selected.

The fuel valves allow the operator to run the engines from the aft tank, which fills from the port gunwale,

the forward tank, which fills from the starboard gunwale or from both tanks.

For normal operation, the port engine valve is turned to the aft tank (tank 1) and the starboard engine valve

is turned to the forward tank (tank 2). The starboard filter supplies the starboard engine and the port filter

supplies the port engine.

If a fuel supply problem should occur in one of the fuel tanks, both engines can be temporarily operated from

either the fore or aft fuel tank. The engines will not draw fuel equally from the fuel tanks when the fuel valves

are set so both engines are operating from both tanks (all four fuel valves open). This could result in one tank

being exhausted of fuel while the other tank is partially full, causing fuel supply problems.

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 GASOLINE ENGINES.

GASOLINE FUEL FILTER

Fuel filters are located in the aft starboard compartment of the cockpit above each

fuel valve. Fuel primers are built into the top of each fuel filter. Primer bulbs are

not used in the fuel lines. The filters are the water separator type and there is one

filter for each engine fuel line. Each fuel filter should be checked for water

frequently to assure an adequate supply of clean, dry fuel to the engines. It is

recommended that the filters are inspected periodically and the elements changed

once a season.
