  1. oh nice, that sounds cheaper than using AN12 fittings like i was. Where did you get the vapor hose and fittings from?

     

    Ebay of course.  Just search "fuel oil hose" with appropriate internal hose diameter (I cant remember what it is right now) and use "elbow" for the 90 degree bends in the right size.  i think my hose was aeroflow. Lots to choose from and really cheap.

  2. The way to shift the bias forward is to cancel the factory proportioning valve, prior to regulating the rears with the aftermarket adjustable proportioning valve. I think you already know this.

     

    The 240z up to 73 had the factory proportioning valve at the rear RHS (and some believe it has residual pressure function too).

     

    After 73 we get the factory proportioning valve on the firewall.

     

    It's not really possible to give a percentage of front to rear bias on a standard 240z as it is not linear. Some people throw 70:30 around which is probably a good average, but the system is designed so that the harder you press the brakes, the more the rears get reduced.
