Fuel Pressure Regulator Conversion KIT RA-series Black Radium Engineering

OVERVIEW
This kit permits all previous Radium Engineering adjustable fuel pressure regulators to be converted to an RA-Series FPR. This will add all of the newest features as well as performance enhancements to older regulators. 

FUEL PRESSURE ADJUSTMENT
RA-series regulators feature the first tool-less pressure adjustment. A jam nut and set screw are no longer required. With a simple turn of the knob, pressure will be increased or decreased.To aid in adjusting pressure, there are incremental detents that provide haptic feedback to the user. Every detent permits 1psi (+/-0.5psi) of adjustment depending on current fuel pressure.

FUEL PRESSURE STABILITY
With years of track and bench testing data, the RA-series regulators have been refined to optimize pressure management. A newly designed single stainless steel return orifice generates laminar flow that enhances stability control.

Minimum Pressure: 18.5psi (1.3bar)
Maximum Pressure: *N/A
*This is rhetorical. The maximum pressure is dependent on the relief valve inside the pump or the maximum current the fuel pump controller allows. 

FUEL COMPATIBILITY
This RA-series conversion kit is suitable with all gasoline types including unleaded, leaded, oxygenated, and pre-mixes. Furthermore, they are compatible with alcohol blends of fuel including methanol, ethanol, and E85.
