3.2 Outboard Fuel System
The outboard fuel system on the Pursuit 3070 Offshore 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.
