3070 OFFSHORE
3.2 Outboard Fuel System
The outboard fuel system on the Pursuit 3070 has two fuel tanks and four manual “ON/OFF” fuel
valves that are labeled to indicate the engine the valve will supply. The fuel valves are located
on the top of the fuel tanks below the inspection plates in the rear of the cockpit. The valves are
off when the handle is perpendicular to the fuel flow. The fuel valves allow the operator to run
the engines from both tanks or from either the port tank, which fills from the port gunnel, or the
starboard tank, which fills from the starboard gunnel.
Proper fuel management is important on all boats. During normal operation, the port engine
should be supplied fuel from the port tank and the starboard engine supplied fuel from the
starboard tank. The fuel valves on each tank are labeled port and starboard. The labels refer to
the engine the valve supplies. If a fuel supply problem should occur in one of the fuel tanks, both
engines can be temporarily operated from either the port or starboard fuel tank by opening both
valves on that tank. The fuel valves on the port tank should be off when operating both engines
on the starboard tank and the fuel valves on the starboard tank should be off when operating both
engines on the port tank. Operating the boat with all four fuel valves open is not recommended
and should be avoided.
Note: 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
THE VALVES BECOME CLOGGED, CLEAN AND REINSTALL OR REPLACE.
Fuel filters are installed in the transom area of the boat. The filters are the water separator type
and there is one filter for each engine fuel line. Each fuel filter has a sediment bowl that 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 as needed.
See Fuel System Maintenance for additional information on the fuel filter.
Note: Some fuel injected engines have fuel filters on the engine and do not allow external
fuel filters. If your boat is equipped with fuel injected engine(s), it may not have a
separate water separator fuel filter.
