FPR Kits?

[Raksj04]

I was looking to get a FPR for my S4 TII. I wanted to know if there were any kits out there and what kinda feed back there was from brand to brand. My fuel lines are stock, so a kit that comes with what I need to install it would be great.

you can do an sx engineering one. use the stock rails,ditch the pulsation damper . order the fittings from jegs or summit and plumb right into stock rails.then again, that all depends on if your running all the emissions, stock injectors, and so on.let me know your set up and I can advise from there.

[Raksj04]

No emissions, It is a JDM motor. I have larger secondries, running Rtek 2.1. I ditched the PD a while ago. I am also willing to change the fuel lines because I sometimes smell fuel but I have yet to see a leak.

ok. this is quite simple then . grab some braided -6 line for the fuel. you can get the fittings from jegs or summit that will screw right into both factory rails .makes for a nice clean install . braided line will go right to fuel filter and fuel return. get an sx engineering regulator 1:1 ratio for boosted motor. set pressure same as stock . youll be good to go. stock rails are quite good so no need to worry there .hope that helps. used many systems like this on many 2nd gens.

What about the SaRD standard FPR or other brands? Does anyone know what fitting will fit into the stock turbo fuel rail? also what is a good source for the -6AN fuel line and recommend lengths.

I recently did a parallel setup and used a Aeromotive A1000-6. But before I did that, I had it setup all stock with just an aftermarket FPR like in the below photo. I used pushlock hose. DO NOT USE summit pushlock hose. It is not rated for fuel for some reason. When I went parallel I used Aeroquip AQP pushlock hose. It looks and feels much tougher, and I haven't had any issues with it with a few months of use, dyno time, and 700 miles of driving to DGRR last weekend.



Completed parallel
Later, I added some corrugated split loom over the lines and some loop tie downs to keep the hose from abrading anything

fitting to screw into the back of the secondary rail. It has a oring/washer combination for sealing.

I got mine all from summit
Aeromotive A1000-6 FPR
Aeroquip AQP pushlock hose
Mix of summit and Aeroquip 45deg, 90deg fittings
*of the two fittings, Aeroquip installed more "confidently" during tightening and felt of much higher quality. I recommend spending the extra few dollars on their fittings or another name brand. The last thing you need is a fuel leak.

what are the benifits of running a parallel fuel system?

When using larger injectors, especially in the primaries, there is less disturbance/spikes/drops/etc to fuel flow for all of the injectors when they click open... there is also increased flow when you run two lines all the way back or in this case use a 3/8" feed instead of the stock 5/16". But, none of this matters until higher power levels anyway.

If you just want to have control over your fuel pressure and have a newer part than a 20+ yr ol FPR... just add a new FPR to the end of the line using the part listed and call it a day.

-6 braided line is 3/8" ID. You shouldn't be just clamping it down on a 5/16" fuel filter outlet. For the return you don't need to change the hose (or at least spend money on expensive hose) because there is no pressure.

that hose isnt cheap. how much did you end up using?

You can see in my pics how much I used.

the minimum on summit was 20ft I believe. Yes, its expensive, and so are the fittings... but they also have less chance of firey death. I'm sure you can find someone on here to ship you a 2ft piece of leftover hose if all you want to do is an FPR on the end.

This will not be a cheap endeavor using AN line. Get used to $10-15 for individual fittings. If you want cheap, I have a new stock replacement FPR (used for 6months) that I will sell you for $35 shipped

I may redo all the lines. I redid them a few years ago but that was with cheap autozone hose and since I sometimes smell fuel when driving I want to be sure that it isn't leaking near the hottess part of the car. Can this hose just be cut?
Thanks for the offer but I am replace the stock one with an adjustable one to help fix an issue I have.

How cheap is "cheap"?
"Fuel injection" hose is very expensive - even from Autozone.
It's going to cost almost the same as this push-on or SS AN stuff.
It should cost close to $10 / foot?
If you paid like $1 - $2 / foot, it's the WRONG HOSE.

I dunno what you're trying to do, but messing with an adjustable FPR usually gets you into more trouble.
At the very least, you need to monitor fuel (rail) pressures to have an idea what is going in.

I had the issue of hesition and wild AFR fluxs when the car is in the closed loop mode. I have a RTEK 2.1 walbro 255 and larger secondry fuel injectors. From what I have read increasing the fuel pressure or just upgrading to FPR to one that can handle the increased flow of the fuel pump will fix the issue. I do plan on getting a fuel pressure gauge with this setup.

Your lean afrs during cruise are not caused by the stock FPR or its lack of adjustment. The Wlabro 255 will outflow the stock FPR and if anything will cause a rich condition, not lean. Raising your static fuel pressure might mask the problem but that's no the same as finding the real source.
