Fuel
System
The generator must have its own fuel supply line; in other words, it must have fis own pickup tubes and
primary filter/water separator.
DO NOT tee off another engine's fuel supply. Installations where the fuel
tank(s) are
at
or
above the generator, with the fuel supply lines
to
the engine's carburetor routed below the
level
of
the fuel tank's top, must have a means
of
shutting off the fuel
to
the generator's engine when the en-
gine
is
not running. This installation procedure helps guard against the possibility
of
gasoline siphoning
through the
supply line into the engine through the carburetor, should the carburetor float needle valve stick
in the open position
or
not seat properly, or should the fuel line rupture between the engine and fuel tank.
This (anti-siphon) shut-off
valve can be electrically-operated (with a manual override)
to
open when the gen-
erator's engine
is
started, and
to
close when the generator's engine
is
shut down. A manually-operated valve
can also be installed and should be operational from the generator's start/stop panel
or
from the vessel's
deck. Installations where the generator
is
located above the fuel tank(s), whereby the routing
of
the fuel
supply line
to
the generator's carburetor remains above the
top
level of the fuel tank,
do
not require this (anti-
siphon) shut-off valve. A manually-operated service shut-off valve should be located between the fuel pick-
up at the tank and the service shut -off valve located at the fuel connection
to
the generator.
The
two
illustrations that follow were taken from the Coast Guard publication Fuel System Compliance
Guideline.
These illustrations show basic fuel system layouts that incorporate anti-siphon protection.
All fuel lines should be routed and supported
to
prevent leaks from vibration and chaffing. The line should
be
supported every
12
-
14
inches. Use as few connections as possible in the plumbing
of
these lines.
The fuel tank's vent should be located so that its discharge route cannot allow water
to
enter through to the
fuel tank(s). Moisture must not be allowed
to
accumulate in the vent's line.
