The hose on the very bottom goes back to the fuel tank.
The hose near the firewall near the bottom is the input to the fuel pressure regulator from the fuel rail.
The vacuum line that is on the side near the middle goes back to the intake baffle tank. Not sure of this function.
The vacuum line on top is from the boost port on the supercharger. It suppose this port is used to control the diaphragm which in turn will help regulate the fuel pressure.

Does the Cartech rising boost FPR (or FMU) have two diaphragms or a valve from the boost port to the main diaphragm? The hose going to the intake box is like the old OEM FPR to maintain the stock fuel pressure.
Once the engine is in boost, the top port on the FPR will hold the diaphragm, thus increasing fuel pressure.
If I'm wrong, please explain.
