Problems With Alcohol In Gasoline; Recommendations; Fueling Instructions - Four winns 278 VISTA Owner's Manual

A. Problems with Alcohol in Gasoline
Below is a list of problems which may be experienced
when using blended gasoline.
1. Premature deterioration of fuel system compo-
nents may occur. Alcohol will attack rubber fuel
hoses, fuel tanks, fuel filters, fuel pumps and
rubber gaskets. This deterioration will lead to fuel
system leakage.
2. Phase separation of fuel will cause contamination.
Water which accumulates in the tank through
contamination or condensation will be absorbed by
the alcohol. This water-heavy alcohol will settle at
the bottom of the tank. This phase separation will
lead to fuel tank corrosion. This may also result in
a lean mixture to the carburetor and cause engine
stalling or possible engine damage.
The use of alcohol additives in gasoline has become
more widespread. Regulations on public notification of
the existence of additives is currently controlled by the
Environmental Protection Agency (EPA). Some states
do require that gasoline pumps display information on
additives (especially alcohol). If alcohol content is not
posted, ask and avoid using fuel containing alcohol if
possible.
B. Recommendations
Assume blended gasoline is being used and follow
these recommendations below.
1. Inspect fuel hoses often. A deteriorated hose
containing alcohol blended gasoline will normally
be soft and swollen. A deteriorating hose contain-
ing no fuel will normally be hard and brittle. In both
cases the hose should be replaced.
2. Ventilate the engine compartment before starting
the engine(s). Operate the engine compartment
blower for four (4) minutes. Then, prior to starting
the engine(s), check the bilge area for the scent of
gasoline fumes; DO NOT start the engine(s) if the
odor of gasoline is detected.
3. Frequently inspect the fuel system fittings. Inspect
the fuel tank, pump and filter for signs of leaks or
corrosion. Visually inspect for deteriorating metal
fittings at the fuel hose connections.
Fuel Systems - Section I
Avoid serious injury or death from fire or
explosion resulting from leaking fuel. Inspect
system for leaks at least once a year.
If areas are found within the fuel system that appear
questionable, have a qualified marine technician in-
spect the system. A thorough fuel system examination
should be made by an experienced marine technician
at least once a year.

FUELING INSTRUCTIONS

1. Avoid fueling at night except in emergencies.
2. When moored at fueling pier:
a. Do not smoke, strike matches, or throw-
switches.
b. Stop all engines, motors, fans, and devices
that could produce sparks.
c. Put out all lights.
3. Before starting to fuel:
a. Ensure that boat is moored securely.
b. Be sure the proper type and grade of fuel
as recommended by your Engine Owners
Manual is used.
c. Determine how much additional fuel is
required to avoid overflow.
4. During fueling: Keep the fill nozzle in contact
with the fuel opening at all times to guard against
possible static spark. See Figure I-6.
Spilled fuel is a fire or explosion hazard.
DO NOT overflow the tank or allow fuel spills
into the hull or bilges. Avoid overboard spills.
When tank is almost full the sound from the
fuel vent will change. The pitch will become
higher indicating the tank is close to being full.
Stop pumping fuel into the tank.
DO NOT TOP OFF.
