Radium Engineering 20-1102 DFPR Dual Fuel Pressure Regulator. Splits fuel delivery into two separate systems at once, for engines that use both direct and port injection and for venturi transfer systems that cannot work with fuel surge tanks.
- Compatible with all gasoline types (unleaded, leaded, oxygenated, premix) and alcohol blends including methanol, ethanol and E85
- Tool-less knob adjustment with detents of roughly 1 psi each (plus or minus 0.5 psi)
- FPR2 is always at or below FPR1. If rising-rate pressure pushes FPR2 above the FPR1 setting, FPR1 rises to match
- Single stainless steel return orifice for laminar flow
- Minimum pressure 18.5 psi (1.3 bar). No fixed maximum, it depends on the pump relief valve or the fuel pump controller current limit
- 360 degree swiveling, double O-ring sealed vacuum reference port with four interchangeable 10-32 fittings: 5mm barbed, 3AN male, push-to-connect for 1/4 in OD tubing and vacuum plug
- Ports: PUMP IN, FPR1 OUT, FPR2 OUT and RETURN, all 3/4-16 (8AN ORB), plus a 1/8-27 NPT auxiliary sensor port for each of FPR1 and FPR2 with plugs included
