Description
BENEFITS:
1.Enhanced
design
allows
easy
fittment
of
"taller"
injectors
such
as
the
HKS
Injectors
2.Each
fuel
rail
can
be
fed
individually
for
equalized
fuel
flow
3.Billet
fuel
rails
have
a
larger
internal
diameter
for
improved
fuel
flow
(approx
500%
improved!)
4,Redesigned
injector
hood
(internal
portion
of
the
fuel
rail
where
the
top
of
the
injector
receives
fuel
from)
that
offers
much
better
clearance
and
flow.
5.Allows
fuel
to
flow
to
the
injectors
easily
for
maximum
performance
These
are
the
first
aftermarket
rails
developed
for
the
350Z
and
G35,
and
their
quality
has
never
been
matched.
Typically,
these
rails
are
used
in
"Return
Fuel
System"
conversions.
Here
is
some
basic
information
on
a
"Return
Fuel
System"
setup
and
its
advantages:
Our
New
AAM
Return
Fuel
Rail
System
is
a
direct
replacement
and
upgrade
to
the
factory
fuel
system.
The
factory
fuel
system
is
a
"return
less"
style
system.
A
"return
less"
style
system
offers
minimal
adjustment
to
the
amount
of
fuel
the
engine
can
receive.
This
can
work
well
in
a
factory
naturally
aspirated
setup,
but
has
several
draw
backs
when
you
go
to
forced
induction.
One
negative
aspect
of
the
factory
returnless
system
is
that
the
factory
fuel
pressure
regulator
is
installed
in
the
fuel
tank.
The
factory
fuel
pressure
regulator
does
not
allow
fuel
pressure
adjustments
and
is
incapable
of
holding
a
constant
fuel
pressure
with
most
aftermarket
fuel
pumps.
The
factory
fuel
pressure
regulator
also
is
unable
to
add
fuel
pressure
under
boost.
Most
factory
turbocharged
setups
use
a
"return
style"
fuel
system.
In
a
"return
style"
fuel
system
the
fuel
is
feed
from
the
fuel
pump
to
a
fuel
filter,
then
to
the
fuel
rails
(which
feed
the
injectors),
and
a
fuel
pressure
regulator
regulates
the
fuel
after
the
fuel
rails
to
keep
a
constant
pressure.
This
systems
allows
a
1:1
fuel
pressure
regulator
to
be
used,
which
will
typically
increase
the
fuel
pressure
one
pound
for
every
pound
of
positive
pressure
(psi/boost)
a
turbocharger
or
supercharger
is
pressurizing
your
vehicle.
This
system
can
also
use
an
adjustable
fuel
pressure
regulator
which
greatly
aids
tuning
on
the
dyno.
