ity of accidental fuel spills. The fuel system on the
Scarab jet boats have automotive style refueling, to
include automatic nozzle shut off and fuel nozzle
retention.
Note: The automatic shut off feature only
exists when dispensing fuel with an auto shut off
nozzle.
NOTICE
Gasoline fuel systems used in Scarab jet boats
are designed to meet or exceed the require-
ments of the Environmental Protection Agency
(EPA), US Coast Guard, California Air Re-
sources Board (CARB), the National Marine
Manufacturers Association, and the American
Boat and Yacht Council in effect at the time of
manu fac ture.
These models include an integrated fuel system which
utilizes a pressurized system. See Figure B24. A
pump pressurizes the system pushing the fuel to the
engine.

Avoid overboard spills. Be alert. The fuel nozzle
should automatically shut off when using an
automatic shut off nozzle. Be ready in the event
it does not or if you are using a different type of
nozzle for dispensing fuel.
DO NOT TOP OFF.

inlet control valve opens and allows the remaining fuel
in the fuel line to drain into the fuel tank.
It should also be noted that when the air temperature
rises so does the pressure in the fuel tank. When this
happens the pressure is released through one or both
the grade valves depending upon the angle of the fuel
in the tank.
