RADIUM Engineering 20-1102 Dual Fuel Pressure Regulator DFPR

The RADIUM Engineering Dual Fuel Pressure Regulator (DFPR) is specifically engineered for high-performance custom fuel systems that utilize both direct injection and port injection. This innovative regulator permits independent fuel pressure control for each system while using a single fuel feed input, making it ideal for modern engines with dual injection systems.

Key Features:

• Independent pressure regulation for direct injection (FPR1) and port injection (FPR2) systems from one inlet
• Tool-less pressure adjustment with tactile detent feedback - each detent provides 1 PSI adjustment
• Suppresses aggressive pressure spikes generated by mechanical high-pressure fuel pumps (HPFP)
• All ports feature 3/4-16 inch (8AN ORB) threads for fuel connections
• 1/8 inch-27 NPT auxiliary sensor ports for gauges and monitoring on both FPR1 and FPR2
• 360-degree swiveling vacuum reference ports with double O-ring seals
• Includes anodized aluminum mounting bracket with M6x1mm hardware and flush-mount stainless steel screws
• Compatible with all gasoline types including unleaded, leaded, oxygenated, and pre-mixes
• Single stainless steel return orifice designed for laminar flow and enhanced stability
• Four interchangeable 10-32 threaded vacuum port fittings included

The DFPR is designed to be plumbed upstream of both the HPFP and port injection fuel rails. FPR1 supplies the high-pressure fuel pump inlet, while FPR2 feeds the port injection system. If the engine lacks port injection, FPR2 can be plugged without affecting FPR1 operation. This premium regulator delivers precise fuel pressure management for demanding performance applications.
