less active metal is decreased, as compared to when

these metals are not touching.

B - 6 FUEL SYSTEM (GASOLINE)

A. Fuel System

The equipment used by Scarab, as described by the

manufacturer, is designed to provide maximum engine

-

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.

Figure B24: Pressurized Fuel System

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.

The location of the tank is forward of the aft bilge
