Default Looking for a bolt on FPR

I'm looking for a bolt on aftermarket adjustable FPR.

I am not going to do the stock FPR modification.

I can see a SARD version and an SX one. Anyone have experience with these? What modifications are required to install these on a WRX with Perrin Rails.

What other options do I have.

Today I am feeling lazy and thought that I would post a question.

Thanks

I have the SX, with MRT rails, so your setup will be better from my guesses. I'm not sure how the perrins are setup at 1st. The SX works with 2 input, and 1 output.
With the SX you can do it a few ways. 1st run them as a dual feed or parrell, each rail gets an input, and an output to the SX unit. Kinda looks like this.
One rail~~~~>SX<~~~~Other rail
l
Perrin Block with stock FPR
l
V
Back to tank
Another way you can do it is run the rail in series, like the stock ones are. On the other input you can run a Fuel pressure guage.

Both rails~~~>SX<~~~~Guage
l
Perrin Block with stock FPR
l
V
Back to tank
On the output hook it up to the stock FPR with the little block that comes with the perrin rails. Then use the stock fuel return to tank If you don't you will loss the pressure in the lines each time you turn the car off, with sux, cuz mine does that. I'm not sure how the little blocks input/output works, my guess is you are going to have to come up with a way to, One split the output from the SX, or Two block up one of the inputs on the perrin block.
There are a few things to think about before doing this. One it is a lot of work to do it, two which setup you want to do. I would say the parrell is the way to go, less risk of one of the rail leaning out. On that setup you can tap one of the inputs for a guage, which is what I did. You can order a small on for like $50 from summit to have right nice to the SX unit.
Hope that helps PM if you have any other qusetions, or need me to make anything clearer.

Edit, I see that the "drawing" aren't working right, but I hope you get the idea.

I try, but there isn't really a "bolt on" one, but if you do the install remember whats a feed and a return, it helps a lot.

Hey Mick. I installed a Sard unit and some perrin rails on a friends car. What I ended up doing was pretty simple.. I took the Perrin FPR "block" and placed it in a vice. I tapped the hole in the block where the stock FPR fits into. I tapped it with a standard pipe thread. Dont remember the size off hand. I then screwed a double male pipe adapter into the perrin block and then into the SARD FRP. I then ran the return line to the Sard and the output line from the rails to the sard. Turned out nice.. cost $1 for the fitting. The SARD sits right where the stock FPR would sit on the Perrin fpr block..

As an alternat you could mount the sard or any type of fpr and then tap the perrin FPR block and then use a 90 fitting to a hose barb.. You could run that where ever you needed.

I used to run a Custom setup with a malpassi RRPR on my car. It worked fine. It was nice to have the adjustability. Now I just have a stock FPR that is crushed in 11 psi static with perrin rails.
