do you need to change the ecu or anything else to run this setup??

kinda off topic? but are there any different types of connectors we can but for the injectors? the one KGparts send are a PITA to unclip.. unless im doing it wrong??

I don't read anything on that here so I assume it was included in the meantime to sit UNDER the spacer (beteen spacer and LIM) in order to add a seal between them.

As has been mentioned in other threads the injector hole in the LIM is drilled by Mazda with a certain tolerance and may need additional sealing.

This is hypothetical, as I see it. Can anybody confirm the position of this O-Ring?

Thx

I have had a few ask me about what fuel line does what on the hardlines that come from the rear to the front. Here is a pic that shows you what one is what, based on you looking into the engine bay from the front.

Braided Lines
This is just a tip on how I used a small screw-clamp as my tool to get the ned fittings on without flaring out all the braids and making it impossible to get the fittings on. Basically I tightened the clamp where I wanted to cut the line and cut it right to the edge of the clamp. Then pushed the clamp back just a bit so there is some hose that can enter the fitting.

Here is a pic with the clamp pushed back a bit after the cut:

Keep the clamp on and tight enough to hold the braided line from flaring out, but loose enough so that it slides down the hose as you push the fitting on:

Below is a shot of my final setup. Notice how I wrapped the braided lines in that black spiral 'stuff'. Its meant to eliminate the situation where braided lines wear away things that they rub against. I also zip-tied them where i could to eliminate any possibility of braided lines vibrating around, everything is pretty tight and moves as one unit.

Basically once you put all the goodies back on the car you cant really see much.

Hello Rotary freinds ;-)

I have bought the RX7 store extreme fuelsystem and are about to install it, unfortunately no installation instructions came with the system ! I have found out I had to completely remove the ACV to get to the seconddary rail, wich is the one that comes with the new system, my question is, can I have the ACV installed with this new rail/injectors ? if not, I guess I would have a ACV block off plate ? that did NOT come with the system, I wonder why ? I still have my sequential turbo setup ! allso, I would get to the secondary fuelrail to get the injectors out and have them tested/cleaned, what do I have to remove/unbolt to get to that ? thank's in advance guys :-)

Rene,
You have to remove the ACV with that. We mention that in the product description. We sell a lot of these kits to those that already have block plates so we don't provide that in this kit. If you need one let me know and I can ship one out.
When taking out the stock injectors you need to take off the upper manifold. Once that is off its pretty straight forward on unbolting the rail.

Ok, so here is my attempt at a comprehensive fuel system upgrade writeup. I need to thank Keith, Steve, and Shawn for helping me a lot in this process.

This writeup will be based on upgrading the primary and secondary rails and injectors, as well as SS braided line for everything in the engine bay to the firewall. My upgrade uses a kit from KGParts.

First lets start by looking at my system before the upgrade, as you will see I already had an aftermarket FPR and the fuel filter was moved up here from the rear.

Here is a drawing to better see how it was:

Here is a picture of the new kit from KGParts:
http://www.myrx7.com/images/new_kg_fuelkit.jpg

The new kit runs a bit differently, the rails are not in series like the stock system, they are in parallel, so they both get their own feed from the main feed line and they get their own return to the FPR.

Here is a drawing of how I planned to run my new setup:

Summary Of Install
1) relieve gas pressure (search forums, there is plenty of info on how to do this)

2) remove all old rails/injectors/lines
keep some towels around as there will be gas in the rails/lines and you want to place towels under these areas before disconnecting. Not a big deal as it evaporates fast anyway. I let a lot dump around and it was gone in minutes.

3) before installing anything, lay it out on the engine where its supposed to go, including the lines. This helps you plan if you need to change line lengths or use different fittings to make the lines go where you want them without kinking them up. This step saved me a lot of trouble in determining the FPR placement and fuel filter placement and what was needed to make both happen correctly.

4) Washed out the rails and checked all the holes for 'hangnails' that could be filed off. You dont want 'dirty rails' going in there :-)

5) Put the sleeves on the injectors, according to the info I got it was the shorter sleeves on the secondaries and the longer ones on the primaries. I also used a bit of motor oil to lube the injector 0-rings.

6) On the primaries, remove the stock diffuser and follow the process outlined below on using them as a seal for the injectors. on the secondaries pull out the old seal and diffuser. The injector install quirks are detailed below. I had to use things that looked like dentist tools in order to get the diffusers out without destroying them. YOU WANT TO KEEP THEM INTACT, YOU WILL END UP USING PART OF THEM.

7) Install the rails, lines, and whatever else you upgraded (fpr, gauge, et)

8) Setup your electrical connectors with the resistors, clip the old connectors and solder the new ones in. Apparently the resistor can go on either side and the connectors wires can go on either wire of the stock connector. Just keep track of what connector goes to what injector.

Those are the basics, here are pictures and details of certain aspects of the install.
