Radium Engineering 20-1102 Dual Fuel Pressure Regulator (DFPR) Universal

Vehicle Fitment

• Universal application - compatible with vehicles using port injection, direct injection, or both systems where independent fuel rails require different pressures.

Features

• Dual fuel-pressure regulator designed to independently manage two fuel circuits (e.g., direct injection rail & port injection rail) from a single feed line.
• Tool-less pressure adjustment knob with detents providing ~1 psi increments for fine tuning fuel rail pressure.
• Anodised aluminium body with integrated mounting bracket for secure installation in engine bay or fuel system packaging.
• Ports: Feed / Return and two regulated outlets, all with 8 AN ORB (¾-16") threads allowing high-flow plumbing compatibility.
• Fuel compatible with gasoline, E85, methanol, and high-octane blends - suitable for high-performance, forced induction or hybrid systems. :contentReference[oaicite:1]{index=1}
• 360° swivel vacuum/boost reference port enabling flexible hose routing and accurate pressure referencing in tight engine bays. :contentReference[oaicite:2]{index=2}
• Laminar flow return design for stable regulation under high flow rates and racing conditions. :contentReference[oaicite:3]{index=3}

Product Description

The Radium Engineering 20-1102 Dual Fuel Pressure Regulator (DFPR) is the ultimate solution for high-performance fuel systems where two distinct fuel pressures must be maintained simultaneously - typically a direct injection rail and a port injection rail. It allows both circuits to be managed from a single feed line while offering individual pressure regulation, simplifying plumbing and reducing complexity in complex builds.

Constructed from premium materials and engineered for motorsport environments, the unit features tool-less adjustment, high-flow 8 AN ORB ports and vacuum/boost referencing in a compact package. Whether you're upgrading to high-flow pumps, running E85, or building a hybrid fuel injection system, the 20-1102 offers the flexibility, stability and durability required. Because it is universal, it does not tie to a specific vehicle year/make/model - making it ideal for custom fuel systems, engine swaps, or race-only applications.
