prop valve just "tee's " the front in/out and restricts rear flow . also trips the light if pedal drop to far from blown line.
I have always just used a tee fitting in the front and one of these in the rear mounted up by the master . few test drives and then forget it . http://www.summitracing.com/parts/sum-g3905/overview/
few extra bucks for this thing would be nice also http://www.summitracing.com/parts/wil-260-11179/overview/
