Return Fuel System

I was curious what people were doing when switching from a returnless system to a return style system. I'm aware that there are many complex options for custom fuel cells with surge tanks and custom baskets, etc, but I'm looking for something simpler for my K24 turbo swap.

My main requirements are to get a boost reference 1:1 FPR into the system, so I can maintain fuel pressure with boost. I have a DW300c already in the tank.

The simplest solution for me is to install the FPR on the feed line and bypass/remove/disable the stock, in-tank FPR. The Haltech setup already runs the fuel pump at full blast like a return style system, but technically, I don't think I would need a return line, yet I do want that, so I would run a return line off my rail back to the tank with a bulkhead fitting into the top of tank.

FBM sells a kit, but I feel like I could piece it together for a little cheaper. Plus, I have a gauge already, and I'm not a fan of purple. The unknown for me is figuring out how to remove and bypass the fuel pressure regulator. The part in their kit looks like a custom machined piece, so I'm curious if anyone else has figured this out. I'll email them and see if they will sell just the bypass. It looks like a -6AN bulkhead fitting on a hose fitting going to a piece in the shape of a fuel pressure regulator.
