Default MSI Fuel System with ID1300 injector install 2011 STI!!

We have all of these parts, what should we do with them? I know, let’s get them installed on our employee Jake’s 2011 Subaru STI! As you can see in the picture below, we are going to install quite a few parts on this thing. Shortly after we get them all installed, we will take the car to get it tuned and get some numbers for you guys!



You can see we have our work cut out for us. In this thread we will be installing the MSI Top Feed Fuel Rail Kit and the Turbosmart FPR-1200 v2 Fuel Pressure Regulator in black! We started the installation by removing the intake manifold to make it easier to access all of the bolts and hoses and lines that we need to remove and replace with this kit. There are several tutorials regarding the removal of the intake manifold so we figured we wouldn’t bore you with that process in this write up. So we will start this how to with the intake manifold on the bench. You will want to remove the bolts holding the factory fuel lines to the intake manifold, and then remove the bolts holding the wiring harness to the intake manifold as well.

We took the wiring completely off the intake to make the instructions a bit more clear.




Once you have those loose, you’ll want to snake the factory lines off of the intake. Since we had the wiring harness removed from the intake already, it was as simple as just pulling them off and setting them aside. If you do not remove the wiring harness, you will have to undo the hoses and separate the pieces of the hard lines to snake them off the intake.
There are a couple of bolts holding the fuel lines to the intake on the ends as well, you will have to remove these to get the fuel rails off the intake.



Now, there are two bolts holding the rails to the TGV assembly, simply take them out of both sides and they should pull out with the injectors, be aware that there might be some residual fuel in the rails and fuel lines, be careful when removing these. You will also need to unplug the clips on the fuel injectors themselves, since we removed the entire wiring harness; we had already done this at this point. You will have to unplug them to remove them from the system.



On this car we installed injector Dynamics 1300cc injectors. Now is the step where we install these. First, you’ll need to place the O-rings on the injectors and lube them with the supplied lubricant, and then slip them in the fuel rail and into the TGV assembly. Now you’re ready to bolt the fuel rails down.

There are spacers that are supplied with the MSI rail kit, you will need to install them between the fuel rail and the TGV assembly to assure proper fitment when tightening the rails down.




Now we can put the fittings on the rails. On both sides you will want to install the “cap” towards the front of the car, then the flare to no flare AN fittings on the rails. The end with the rubber O-rings go towards the rails, make sure you lubricate the O-rings prior to tightening these fittings.



Install the passenger side return line onto the rail. This is the longer hose that has the 90 degree fitting on one end and a 45 degree fitting on the other end. Connect the 90 degree fitting to the back of the passenger side fuel rail and route between the intake manifold runners and over the intake tube.






Install the passenger side feed line onto the rail. This line is the shorter hose with a 90 degree fitting on one end and 45 degree fitting on the other. Attach the 45 degree fitting to the middle fitting on the rail and route the same as the passenger side return hose.

MSI FUEL SYSTEM INSTALL CONTINUED


Moving on to the driverís side, we can install the fuel lines on the rail. Take the hose that has a 45 degree end on one end and a straight fitting on the other end and thread the 45 degree end on the middle barb on the fuel rail. Then thread the remaining line with straight ends on both to the end of the rail.




Now we are ready to place the intake manifold back on the engine. I found it VERY helpful to have an extra hand here to help guide it back into place.



Now we can assemble and install our fuel block. The main feed and return lines are push on type barb fittings, every other port should have an AN flare/non flare fitting. Once you have it assembled, you can mount it to the pitch stop mount. If you are using an aftermarket fuel pressure regulator, like we are in this installation you will have to buy the block off plate with o ring for the OEM regulator mount. You will also use the supplied push on hose fitting on the bottom of the distribution block.

NOTE: keep in mind that this setup is for an aftermarket fuel pressure regulator only. If you intend on using the stock FPR, it simply mounts to the fuel block.




If you are using the factory fuel pressure regulator, some of these instructions will not apply to your install.

Now we need to install the fuel pressure regulator. After looking around for a while, we found that the best place to mount our Turbosmart fuel pressure regulator was right where the plastic hose retainer clips were from the factory. On the driverís side strut tower. Just pull the stock clips off, and use the hole that the clips came off of to mount the bracket that came with the FPR.








Now we can hook up our fuel lines from the block to the respective locations.





So, that does it, now you will likely need a tune on your car if you have upgraded your fuel injectors during this process. We will get some dyno numbers when this is all said and done, then get them posted up for you guys! Thanks for reading and we hope this helps you out.

Bump for a great reference for your fuel system install needs!

Regards,

I actually installed this kit on my 04 STI with JDM Top feeds and ID1000's per Corby's (the guy who made this install) instructions. And the install went very well and easy! I was worried about not having teflon on the fittings, but I hooked up a manual switch to my fuel pumps and so far so good!








Kind regards,

Jeff

Sorry for reviving an old thread, but I had a question about the routing of the fuel lines with these rails. Is there a reason why one of the ports on each side is blocked off instead of just attaching the fuel lines to each side of the rail? The only reason I ask is because I know certain fuel rails allow for fuel dampeners to be fitted directly to the rails. Do these rails have this capability, or is this the only possible way to attach everything? Thanks in advance!
