Yup... sooo... couldn't find a thread that explained how to do this.. I googled(Maybe should have altavista'd? or Yahooed? dunno) and found one a VW... which is surprising similar or not so... but here ya go for a 2010 Taurus... I apologize if someone already did a write up....
You will need:
18MM Wrench
T45 Torx Bit or Socket
Flat Head Screw Driver
Smaller wrench to depress schrader valve.. or finger nail..
Eyeballs... hands... etc..
Maybe gloves if you are paranoid like me..
Turn the car off... sorry.. I work with really dumb people sometimes.. myself included..
Pop hood.. etc...
Remove the really spiffy SHO engine cover...
On a COLD engine disconnect the battery...
On the passenger side right right under the cowl there is a grey schrader valve cap... remove it.. It is circled in red... and yes.. thats a diaper under it to catch any gas coming out... most absorbent material known to man.. if you have kids... you understand...
Using a smaller wrench or a finger nail, depress the valve to release pressure...I recommend a wrench or philips head screw driver...
On bank 2 (which is the one close to the radiator) there is a silencer made of foam.. just pull it off with you hands (see required tools above.. and yes.. that includes you)...
You will see the HPFP sitting right under it...
Disconnect the wiring going to it by using a flat blade to lift the tab over the catch..
Loosen and slide the nut down holding the fuel line going to the fuel rail using the 18MMM wrench, its circled in green...
Using the 45T Torx bit/socket alternate loosing the screws on either side circled in red... this is spring loaded, so make sure you alternate sides... you do not want to damage it or cam shaft follower inside...
Once those screws are removed, lift the HPFP gently.. it should pop up, and you can rotate it a bit...
Circled in yellow is the quick disconnect fuel line, press the black tab into the line, you should feel or maybe hear a click.. then pull the HPFP away...
Set the HPFP to the side or toss it to the side.. I am assuming you are replacing it...
Using your fingers slide the cam shaft follower out.. it should be fairly easy. You are doing this for two reasons... to make sure the follower is not grooved and to make sure the cam shaft is
not grooved.
If they are then shame on you for not doing regular oil changes... but I digress...
Once checked, you can slide it back in, its keyed with a notch so you can't mess it up... align the notch with the dimple and you are good to go..
To install the new HPFP follow in reverse...
NOTE: The nut on the fuel line to the rails, start it before tightening to the fuel pump all the way.. it may not line up correctly otherwise... at least for me...
NOTE: There are two posts to help you alight the HPFP... this is where your eyes comes into play... and also short term memory... if you try to put it in upside.. you should not be tackling this project IMHO...
***Livernois Motorsports Firestorm HPFP Addendum****
Follow the above instructions to remove the stock HPFP...
The installation of the new pump is fairly simple, follow the instructions to install the HPFP as outlined in this HOW TO but with the following exceptions..
1: This is a two piece pump, so the base plate is help down using the stock T45 bolts. The actual pump is held down by the two allen screws on the stop. To screw the base plate down you will need to twist the stop portion of the pump so allow access to the screws.
2: Bend the HPFP outlet line out of the way but bending it up slightly.
3: Once the base plate has been screwed down, twist the pump back and drop the allen screws back into the top. This will lock the pump in place where it needs to be. Slowly tighten down the allen screws alternating back and for until its tight. This is a spring loaded pump so you will HAVE to alternate back and forth slowly... or you can damage the pump/screws/etc...
This video is for the XDI, but the install is very similar minus the replacement fuel line and pig tailhttps://www.youtube.com/watch?v=eqnewM691Fs4: In the following picture is the silver high pressure fuel line. It will need to be bent it to align with the new outlet for the Firestorm pump. It wont need to be moved much, just a hair to get it to line up.
5: This picture illustrates the low pressure feed line, you just connect it to the low pressure inlet on the pump..
6: This part is a bit annoying and I mentioned to LMS that the pig tail connector to extend the stock connector should be included in this kit. But you will need to peel back the tape on the wiring harness that houses the electrical connector for the HPFP and pull the wiring out. This is needed to give you enough room to connect the plug. Do NOT run it over the HPFP as I had initially did, the pump gets too hot and will melt the wiring.
