SYSTEM OPERATIONS-38
Fuel Supply Valves
If your 43SB is powered by gasoline en-
gines, it is equipped with an anti-siphon
valves; located on each fuel supply hose
at its connection to its fuel tank pickup
tube. The purpose of the anti-siphon valve
is to immediately stop the fl
ow of fuel from
the fuel tank in the event of a break in the
fuel supply hose. The anti-siphon valves
are automatic and do not require manual
operation.
Fuel Filtration
The fuel that is supplied to the engines
and generator (if so equipped) may con-
tain impurities found in the fuel tanks or
contained in the fuel from your supplier.
If these impurities are not removed prior
to entering the engines/generator, perfor-
mance may be seriously affected. Remov-
al of the fuel impurities is accomplished
by external fuel fi
lters, which are located
within the fuel supply line.
If your 43SB is equiped with gasoline en-
gines, each engine has its own separate
fuel fi lter, located on the forward inboard
side of the engine.
If your 43SB is equiped with diesel en-
gines, each engine has has a separate
fuel fi lter located away from the engine.
If your 43SB is equipped with a genera-
tor, a remote fuel fi lter with a fuel shut-off
valve is located in the main generator fuel
supply line, separate from the engine fuel
supply lines.
The photo below shows the generator fuel
fi lter.
An Authorized Silverton Service Techni-
cian should replace all fuel fi lters annually
prior to spring launch.
Fuel Gauge
The purpose of the Fuel Gauge is to allow
you to constantly monitor the fuel level
in the fuel tank. The Fuel Guage on your
43SB is located at the Helm Station. The
photo below shows the Fuel Gauge at the
Helm Panel.
