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 lift pump's ability
to
draw fuel through them.
A check
valve can trap debris under its seat which inhibits the valve's ability
to
close. In ad-
dition,
if
a check valve's cracking pressure
is
100
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 lift pump from drawing fuel through the valve.
Strongly recommended
is
the installation of an approved filter/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 lift pump and carburetor.
IWARNING\
Gasoiine
ieakage
in
or
around
the
generator
compartment
is
a
potential
cause
of
fire
and/or
explosion. Repair leaks promptly and make sure the compartment
is
property ventilated.
