300
Degree
High
Performance
Fuel
Rails
fit
the
OEM
newer
style
of
injectors
(pintle-less)
or
Sard
style
injectors
into
either
style
lower
intake
(early
or
later).
A
common
upgrade
is
to
install
the
newer
style
pintle-less
OEM
injectors
on
an
earlier
model
Z32
replacing
the
pintle
type
injectors.
In
the
past,
the
labor
required
to
complete
this
conversion
involved
not
only
removing
the
intake
manifold
to
access
the
fuel
rail
and
injectors,
but
removal
of
the
timing
belt
and
most
of
the
front
of
the
engine
to
remove
the
lower
intake.
The
lower
intake
is
then
removed
and
sent
off
for
machining
to
accept
the
later
style
fuel
rail.
We
developed
our
rails
to
make
this
upgrade
simpler.
We
avoid
all
the
additional
labor
and
downtime.
Our
rail
will
adapt
the
pintle-less
injectors
to
the
early
style
lower
intake
directly.
Everything
is
a
simple
bolt
on.
300D-012-01
fits
Sard
injectors
(commonly
sold
as
850cc/min)
onto
an
early
model
lower
intake.
300D-012-02
fits
Sard
injectors
onto
a
late
model
lower
intake.
300D-012-03
fits
pintle-less
injectors
onto
a
late
model
lower
intake.
300D-012-04
fits
pintle-less
injectors
onto
an
early
model
lower
intake
(shown
above).
Advantages
to
our
design:
#
Bolt
on
application.
Absolutely
no
major
machining
or
fabrication
required.
For
pintle-less
injectors
with
the
early
plenum,
there
is
a
small
amount
of
grinding
to
make
the
#1
injector
fit.
(Better
than
Stock
and
the
Border
aftermarket
fuel
rail
depending
on
injector
choice)
#
Can
be
plumbed
in
serial
or
parallel.
Installation
flexibility
is
user
definable
for
performance
applications.
The
installation
of
a
parallel
feed
system
should
aid
in
preventing
fuel
starvation
in
cylinders
5
and
6
as
is
common
with
a
stock
setup.
(Better
than
Stock)
#
Has
57%
"faster"
pressure
recovery
then
a
stock
fuel
rail.
The
300
Degree
rails
maintain
pressure
longer
then
a
stock
fuel
rail
while
regaining
fuel
pressure
quicker
with
out
hindering
fuel
flow
below
the
delivery
rate
of
the
stock
fuel
pump.
(Better
than
Stock)
#
Increased
fuel
velocity
when
pressure
begins
to
drop
which
assists
in
the
recovery
of
fuel
pressure.
This
will
be
beneficial
for
those
that
run
Nitorus
Oxide
Injection
systems
where
the
fuel
pressure
drops
to
undesirable
levels
during
NOS
injection.
(Better
than
Stock
and
Border)
#
They
are
completely
thermally
isolated
from
the
upper
and
lower
plenums.
The
stock
fuel
rails
are
thermally
isolated,
the
border
fuel
rails
are
not.
This
can
lead
to
heat
soaking
of
the
fuel
rail,
increasing
fuel
temperature.
(Better
than
Border)
#
Fuel
injector
to
main
bore
alignment
is
optimized
for
maximum
fuel
delivery.
(Better
than
Stock
and
Border)
#
Absolutely
the
highest
and
tightest
tolerance
for
all
threads
where
the
AN
fittings
attach.
This,
coupled
with
an
interference
fit
and
o-rings,
provides
the
greatest
defense
against
fluid
leaks
between
the
rail
and
the
plumbing.
Kit
includes
2
fuel
rails,
injector
caps,
all
mounting
hardware.
Kit
does
not
include
injectors,
injector
seals
or
insulators,
fuel
line,
fuel
line
fittings
or
gaskets.
