The CZP In Tank Fuel Pressure Regulator Elimination Kit allows those with custom fuel return setups to maintain full functionality of the stock fuel tanks venturi system.

The factory fuel pressure regulator lives in the fuel basket and relieves into internal passages that lead to a venturi that draws fuel from the passenger side of the tank. When installing an aftermarket fuel pressure regulator it is necessary to remove the in-tank regulator, this would normally cause the venturi system to stop working. This kit not only comes with a bulkhead fitting to route your -6AN return line back into the fuel tank but it uses that return fuel to feed the venturi system. Without this product your vehicle will run out of fuel while the gauge is somewhere just below the half tank.

This kit compatible with all 350Z, and with G35 Coupes (Does Not Fit Sedans)
