Chaparral 420 PREMIERE, Руководство владельца/оператора

Страница: 69 / 164

Here you will find detailed information about the fuel
systems needed to operate your boat. The fuel sys-
tem provides a clean, continuous supply of fuel to
the engine, in addition to helping prevent possible
fire and explosion.
Note: Refer to your engine owner’s manual for
detailed information about checking and main-
taining the fuel system.
The fuel system must be inspected frequently and
maintained regularly. Check for leaks and/or vapors
and repair any problems
immediately . Keep the
fuel tank filled during the boating season to prevent
moisture from condensing in the tank.
Fuel lines, filters, and all fuel system components
should be checked at the start of each season and
periodically thereafter, particularly after any work
has been done aboard the boat that might have
affected any part of the system. Be certain that
everything is in proper condition and that the entire
system is fuel tight. Each fuel tank has manual shut-
off valves at its top to close off the fuel system in
case of leakage or line failure.
FUEL TANKS
The Chaparral 420 Premiere has two aluminum fuel
tanks with a capacity of 150 gallons (567.8 liters)
each, for a total capacity of 300 gallons (1,135.7
liters). The fuel fill inlets are located on the port and
starboard gunwales outboard of the swim platform.
Your boat is equipped with a fuel tank vent for each
tank that serves as a pressure/vacuum release and
safety overflow. The fuel tank vent allows air to
escape as the tank is being filled and helps equalize
tank pressure as temperatures change. The tank
has an anti-siphon valve that keeps fuel from leak-
ing into the boat in case of fuel line breaks. The
through-hull fitting has a flame arrester, making it
imperative that you keep the screen clean and in
excellent condition. Replace the screen immediate-
ly if it becomes damaged or displaced. Periodically
check the vent to assure that it is not clogged.
FUEL RECOMMENDATIONS
For the highest engine performance and long
engine life, it is important to use quality fuel. Fuel
should be clean and free of contamination. Your fuel
tanks should be kept full of fuel whenever possible.
This will reduce the amount of water condensation
and possibility of contamination.
