tank should a line rupture. See Figure F1 for anti-syphon
location.
F. Fuel Sender
The fuel sender consists of a mechanical arm with float
which measures the fuel in the tank. The sender arm
adjusts with the amount of fuel in the tank and sends a
signal to the fuel gauge. See Figure F1.
Due to the mechanical nature of the fuel sender, varia-
tions in readings during various speeds of operation may
occur. This system is merely a relative indication of the
available fuel supply and not a calibrated instrument.
Relative adjustments can be made by your Four Winns
dealer by bending the fuel sender float arm.
G. Fuel Filters
Fuel filters are installed on each engine. Filters should
be replaced to assure an adequate supply of clean, dry
fuel to the engine. Refer to the engine manufacturer’s
manual for additional information.

H. Gas Vapor Detector
A gas vapor detector is optional on 278 Vista model. The
gas vapor detector will monitor the engine compartment
and notify the operator of an accumulation of gasoline
vapors. The operator must take immediate action upon
warning to avoid the possibility of an explosion.
The fuel withdrawal is positioned in the fuel tank
toachieveoptimumfuelusage,andfuellinerout-
ing. At certain speeds and hull trim angles, the
fuel supply at the withdrawal can increase or
decreaseaccordingly. Beextremelycarefulwhen
attempting to operate the boat on a minimum
amount of fuel. Though some fuel may be in the
tank,therelativetrimangleoftheboatmaycause
the fuel to flow away from the withdrawal.
The sensing unit is usually mounted towards the rear of
the engine compartment. The alarm unit is mounted at
the dash.
Always personally inspect the engine compart-
ment and sniff for fuel vapors before starting the
engine. Remember, a gas vapor detector is a
mechanical device. DO NOT rely exclusively on
its operation.
