Fuel Pressure Regulator -6 AN Fitting Kit
-6 AN Fitting Kit compatible with Fuel Lab Mini Fuel Pressure Regulator.
Return style fuel system layout uses 2 6AN males and 1 plug. Dead Head layout uses 3 6AN males.
Use the chart in the third picture to determine your layout preference. Don't be confused by the names, they both return fuel to the tank. To simplify - if you have two fittings on your fuel rail for fuel in and out, use the return style layout. If you only have one fitting on your fuel rail for fuel in, use the dead head layout.
