Radium Engineering Multi-Port Fuel Regulator

The Radium Engineering Multi-Port Fuel Regulator (MPR) in black is a high-performance fuel pressure regulator engineered for both simple and complex fuel systems. Its innovative design allows you to easily combine dual fuel pumps into a single feed line or split one feed line into a dual fuel rail setup, making it a versatile solution for high-flow performance applications. Whether youre running a single fuel rail, dual banks, or a multi-pump setup, the MPR offers unmatched flexibility, precision, and reliability.

This Radium fuel pressure regulator features multiple port options that simplify installation by eliminating the need for extra Y fittings. The lower opposing return ports are designed for parallel flow with the pressure ports, improving efficiency and allowing for cleaner, more compact plumbing. The unit can be wall- or floor-mounted using the included M6 hardware and mounting bracket, making it adaptable to nearly any engine bay layout.

Built on the proven RA-Series regulator platform, the MPR introduces a tool-less pressure adjustment knob for easy fine-tuning. Each incremental detent equals roughly 1 psi of pressure change, allowing for precise control with tactile feedback. The 360-degree swiveling vacuum reference port with double O-ring sealing makes installation simple while ensuring leak-free operation. Whether youre tuning a high-boost turbo setup or a naturally aspirated performance engine, the Radium MPR maintains stable and consistent fuel pressure under all conditions.

Constructed from high-quality anodized aluminum and finished in a sleek black coating, the MPR offers both durability and style. Its fully compatible with gasoline, methanol, ethanol, and E85 fuel blends, ensuring long-term reliability in any high-performance environment. The regulators internal stainless steel return orifice promotes laminar flow, providing rock-solid fuel pressure stability even under extreme demand.
