When
injectors
are
upgraded,
the
fuel
pressure
controlled
by
a
factory
fuel
regulator
may
become
too
low,
and
injectors'
atomization
performance
may
be
deteriorated.
To
improve
such
conditions,
HKS
Fuel
Regulator
can
adjust
the
fuel
pressure
appropriate
to
injectors'
capacity.
Also,
HKS
Fuel
Regulator
can
increase
the
fuel
pressure
without
replacing
injectors
to
increase
the
amount
flow.
(Extreme
initial
pressure
change
may
cause
bad
atomization.
Also,
it
increases
the
load
to
the
fuel
pump;
in
this
case,
the
fuel
pump
may
have
to
be
replaced.)
