Radium Dual Fuel Pressure Regulator (DFPR)

Radium Engineering's Dual Fuel Pressure Regulator (DFPR) manages separate fuel pressures for direct injection and port injection systems within custom fuel rails, using a single fuel feed to feed both circuits while preventing the high-frequency pressure spikes produced by mechanical HPFP (positive displacement plunger-type) pumps. The DFPR architecture lets tuners and fabricators independently control FPR1 for direct injection and FPR2 for port injection, simplifying integration of mixed-injection setups and improving fuel pressure stability.

Features:

• Designed for dual DI and port injection
• Allows independent fuel pressures per circuit
• Single fuel feed input for both systems
• Suppresses HPFP-generated pressure spikes
• FPR1 for direct injection regulation
• FPR2 for port injection regulation
• Engineered for custom fuel system integration
