    Default Renault Lugna V6 fuel pressure regulator

    I have a question about the set up of the fuel pressure regulator on a Renault Laguna 3L V6 engine .
    I bought the motor from Alpine Affaire and I am going to fit it into my 504 rally car .
    The motor came with its origional fuel rail and injectors with fuel pressure regulator The fuel pressure regulator is a funny looking thing and I do not know which is the pressure supply side and the low pressure return.

    The two hoses have colour coded ends in green and red ( see photo ) could somebody with a Luguna please go and have a look under the bonnet and let me know which is supply and return.

    Many Thanks
    Andy

    Hi Andy,
    The inlet is the end closest to the flywheel, but as it is off the motor, closest to the pressure buffer, not the regulator.

    Thanks Bill

    I take it that the buffer end is the dome without the vacume pipe fitting and that the end with the vacume pipe is the fuel pressure regulator and out let.

    Thats right.
    I was wrong saying the inlet was toward the flywheel! I forgot that my inlet manifold is reversed.
