VALVE
NOTE: The use of mechanical spring-type check valves instead of a solenoid shut-off valve
is
not recommended since these may tax the fuel pump's ability to draw fuel through a check
valve. A check valve can trap debris under its seat which inhibits the valve's ability
to
close.
In
addition, if a check valve's cracking pressure
is
too
high, this can contribute to vapor lock.
Should a mechanical type, spring-loaded check valve
be
used, it should
be
an
adjustable type,
such as a Weatherhead
#43
x
6.
This adjustable type valve should
be
adjusted
to
have a
cracking pressure that
will prevent siphoning when the generator
is
not operating but not so
excessive as
to
prevent the fuel pump from drawing fuel through the valve.
The
installer
should
install an approved fuel filter/water separator in
the
fuel
supply
between
the
fuel
tank
and
the
generator's engine
to
help remove contaminants in
the
fuel before
the
fuel reaches
the
engine-mounted fuel
pump
and carburetor. Such contaminants can cause
the
failure
ofthese
system
components
and
such
failures are
not
warrantable. Owner/operators are advised
it
is
their
respon-
sibility
to
maintain filter/separators so
that
contaminants
do
not
reach
the
engine's fuel system.
Gasoline leakage in
or
around the generator compartment
is
a potential cause of fire and/or
explosion. Repair leaks promptly and make sure the compartment is properly ventilated.
