N54 /2011 n55 hpfp overdrive. Ran this on my car for about 2 k miles before I decided to switch up my build a bit and go port injection. Works good last pull I did on it was at 30 psi with plenty of rail pressure. $500 obo for everything pictured. I have the fuel line they provide somewhere just have to find it.

I am having an issue and have the same kit. How is your car running since the swap?
I have been getting stuttering on hard acceleration or bucking feeling. Finally I got a cel and code for low pressure at hpfp. The hpfp is new with the helix 3x overdrive kit. lpfp is stage 3 with spool.

It may be that the high pressure rail sensor is dying and also in the other thread make sure you can log lpfp to see if your low side is even able to keep up
