Fuel System - Sea Ray 19 SPX Owner's Manual

When washing down, or at any other time, take
care that water does not enter the air inlets. Water
entering the air inlets when the engines are not
operating may go directly into the cylinders, resulting
in rust and possibly internal engine damage.

Tern rive YsTeM
A stern drive propulsion system, also known as an
inboard-outboard engine, has the engine inside the
boat secured to the hull's stringers at the rear end of
the hull. The stern drive unit, also called the outdrive,
attaches to the outside of the hull or transom. The
stern drive unit pivots to steer the boat.

The gasoline fuel system on your boat consists
of a fuel tank, fuel demand valve, fuel tank vent,
anti-siphon valve, engine fuel supply line and fuel
fill. Your vessel contains a new EPA certified fuel
system. The system prevents spit back when filling
the tank and lowers the out gassing emissions
through the tank and vent.

• If an engine running problem is diagnosed as
fuel starvation, check the fuel demand valve.
• If the valve is stuck or clogged, turn OFF the
engine and replace the valve.
• Except in an emergency, NEVER run the engine
without the fuel demand valve.
The Fuel Demand Valve (FDV) is a vital fuel system
part. The FDV prevents pressurized fuel from
entering the engine during the daily heating and
is a
®
cooling of the fuel system.
The valve is located in the line on the fuel hose,
where the fuel feed line attaches to the tank. The
valve is only opened by the fuel pump vacuum.

Never start an engine until you are certain that fuel
fumes are not present in the engine compartment
or elsewhere in the boat.
Your boat is equipped with a fuel tank vent for each
tank which serves as a pressure/vacuum release.
The thru-hull fitting has a flame arrester, making it
imperative that you keep the screen clean and in
excellent repair. Replace the screen immediately
if it becomes damaged or displaced. Periodically
check the vents to assure that they are not clogged.

GASOLINE RECOMMENDATIONS
Minimum octane rating of 87 AKI.
The use of improper gasoline or additives can damage
your fuel system and is considered misuse of the
system. Damage caused by improper gasoline or
additives WILL NOT be covered under warranty.
The quality of the fuel is very important for
satisfactory engine performance and long engine
life. Care should be taken to select fuels having
the octane rating recommended for the engine,
as indicated in the owner's manual, for proper
operation. Fuel should be clean and free of
contamination.
