Adding 30# SVO Fuel Injectors

By IBxAnders - April 21, 2010

Thanks goes out to
DV-8 (aka Johnny)
from Houston. He was kind enough to help out and take some good
pics.

Tools Needed:

10mm wrench and/or
socket and ratchet
small flathead
screwdriver.

Installation
summary:

Remove
the
fuel rail covers (if you have them).
I
hadn’t driven it for about 24hrs, so I placed a rag over
the end of
the fuel rail pressure relief valve, and
pressed the valve to depressurize
the system. It had
already depressurized naturally overnight. So no
gas came
out.
Take
out the
bolts that hold the fuel rail down. 4 of them.
Push
the silver clips that hold the harness to the each
injector inward,
and pull the harness connections off each
injector.
Disconnect
the main electrical connector to each side of the fuel rail.
I also unhooked the connections to the throttle body to make things
a little easier.
Then
once the
fuel rail is loose grab one side broadly and pull up firmly
to get the injectors out all at once from the manifold.
Repeat
for the other side. (wiggling helps while
pulling up).
Its
MUCH
easier to lift all the injectors out from the manifold while
they are still on the fuel rail then to try to pull them out from
the fuel rail first, so don’t try to lift the fuel rails off the
injectors
while they are still in the intake manifold.
You will most likely
bend or break the fuel
rails.
Used
a flat
blade screwdriver to pop out the small black metal retaining
clips that hold the fuel injectors to the rail. These are kinda
like U-clips, and they come off towards the inside of the rails.
Take them all off and set them aside.
Once
there all popped out I choose to remove the gray plastic
retaining
tabs that holds the harness to the
rail.
Pull
the the
whole fuel rail up and out as far as it can go.
With
the injectors sticking up now, pull very
hard to get them out. The
O-rink on the top of the
injectors may stay up inside the socket,
so have a small
screwdriver handy to pull them out. It easily came
out
after the injector was out. Put the o-rings back on the injectors
once out.
Then
by hand
press the new injectors in the fuel rail. Not to difficult,
but some of them may require some grunting and cussing.
Now
put the little U-clamps on the tops of the
injectors.
Re-position
the fuel rail and align all injectors in their holes and press them
in using the fuel rail. You will hear each of them pop in.
The mount points that the four bolts go in, should be sitting flush
with the mount point. If there is a gap, then you have an injector
that’s not fully seated.
Then
reconnected each electrical plug for each injector. Reconnect
the main electrical connector to each side of the fuel rail.
Don’t forget the throttle body connectors too if you unplugged them
earlier.
Turn
the key
to the on position, without starting, to let the system pressurize.
Check for leaks. Do this several times. Once you are absolutely
sure there are no leaks, then start it.

Good comparison of the size difference. Keep in mind that
these are rated at 30# at the Ford fuel pressure level. Given
our higher fuel pressure level, they flow about 36#
