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

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.
