This crazy product has never been done before for the automotive aftermarket. The Radium Dual-Fuel-Pressure-Regulator (DFPR) features two fully functional, independent, EFI fuel pressure regulators in one compact unit.
The obvious question is…why do I need this? This product was intended for use on vehicles that have direct injection (DI) and aftermarket port injection (PI). Radium Engineering offers port injection add-kits for several vehicles.
With the DFPR, the fuel pressure for the DI system (going to the high pressure pump) is independent from the PI pressure. This allows independent pressure adjustment of the two systems. This also isolates the PI system from fuel pulses created by the DI high-pressure pump. Starting at: $299.95
