I’m thinking about setting up a return fuel system. That FBM kit seems fine, but I figure it could be done cheaper. I already have a fuel pressure sensor and in-engine-bay fuel pressure gauge like what they provide in this kit. I need a boost reference FPR, return line and whatever modifications or adapter needs to go to the pump. I have a DW300c already. Looking at their kit, it seems like there is a custom machined adapter, so unless I can get that by itself, I’m not sue how to piece the kit together. Any ideas?
I’m also not entirely sure about the setup. I need to look at my fuel rail again because I remember thinking the return port on the bottom of the fuel rail seemed like it was awfully close to the intake manifold making a fuel return line or fitting hard to impossible to fit. The FBM kit seems to bypass the stock fuel pressure regulator in the tank, while having a fitting for the return line, but I’m not sure exactly how it is all hooked up. I don’t see installation instructions. Where does the hose come into the tank? Where does the new FPR go?
My main goal is to keep fuel pressure up during boost, and so I can add more boost on the current injectors when I do the transmission upgrade.
