I notice that you got the FST with the integrated fuel pressure regulator, If I remember correctly this system is only supposed to be used with a 'deadhead' return-less system as there are only 3 ports. ISF's are set up as return type from both the engines Direct & Port injection. How were you planning to plumb this in? The only way I see this working would be less than ideal, but suppose you can cap one of the 3 ports on the surge tank and have the OEM fuel rail return line going back to the OEM fuel tank like normal. Then one of the remaining ports would be going out to the rails and the other would be getting fed from the OEM fuel pump. Like I was saying though, this wouldn't be ideal from a couple reasons.
1. your going to create high a pressure situation inside the sump canister becasue there will be no relief path for the fuel to travel out of the sump tank other than to the rails (which will only works when the car is running and under load) You can quickly kill the pump or have a line/gasket failure. (yikes)
2. you wont have the benefit of refilling the sump tank with fuel return as it will be going directly back into the OEM tank instead.
Am i missing something here? Did you install it yet?
This is the RR racing kit, so it was used by some of the members here. And they dont have any problem with the kit.

I had the Tillett version of these and man are they light. Despite the positive reviews on comfort, my spinal problems just didn’t get along with the seats, so I switched to carbon recaros with more cushion. You’ve probably dropped about 80 to 90 pounds though. It’ll be noticeable.
I’ll be shocked if you can see over your wheel without some higher brackets or sliders. I needed a slider to bump me up high enough. Those seats without sliders are LOW!

This seats are hard to my butt bones, i used the comfort of my sparco qrtr. But this is 3lbs lighter than the sparco. Try to find cushion upgrades.
Now, my F can keep up with the typeR at turns. No fuel starving after the radium fuel pump installed. This is a 400HP typeR. https://youtu.be/AC62NDuYtFQ
So far this is my F best performance in the corners, quite an achievement. Without the OSGiken this cant be achieve. I believe no F can match the cornering power of CTR without the OG. Penskes or ohlins may or maynot improve the performance but im more inclined to change my wheels from 18/10 to 18/11 rear, to settle the movement during cornering. In terms of suspension the 18/16 spring rate is not quite enough. Im upgrading to 20/20.

I'm also on RR R&T coils, OSG diff and APR GTC300 wing and just went from 16/12 to 16/16 rates. Definitely brought out the oversteer. I've only got one track day with the stiffer springs, so it will take some getting used to.

Seems like my set is still soft, thats why im upgrading to 20/20 Love the color combo too, lol
So excited about the result of my 20/20 spring rates, the car is more planted in the corners, i expect it harsh but is not. Like to go to the track but i have a starter breakdown unluckily. So more tuning to be done in the car. Rr racing arms are coming.
