3.2 Gasoline Engine Fuel System
The fuel system on the Pursuit 3000
Express 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 per-
pendicular 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 GASOLINE ENGINES.
