Adding 30# SVO Fuel Injectors

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#	It’s tight up under there. You Corvette guys have it easy.
Here’s about halfway through. Notice the injectors are already gone. The last one back there was tough….VERY tough.	Another angle to give you an idea of how little room us F-Body guys have to work.
Aerial view….	That’s where they go… Notice the bolt hole to the top right. That’s one of the four mount points for the fuel rails.
Same shot, a little closer	Notice the excess fuel that spills out into the hole… Make sure you are in a ventilated place when you do this… We were seeing weird colors….
All injectors out at this point… Taking a breather…	Another shot. As you can see it’s not very roomy, and I’m actually up on top of the engine.
ACTION SHOT!!! Yes those injectors are in there good!	Here I’m still trying to get them all off.
Oh yeah! Looking good!	There’s what they look like when they’re done.
Finished product.	After breathing gas fumes for about an hour… I was relieved that it all worked!
