PRODUCT DETAILS
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 you’re 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 you’re 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. It’s fully compatible with gasoline, methanol, ethanol, and E85 fuel blends, ensuring long-term reliability in any high-performance environment. The regulator’s internal stainless steel return orifice promotes laminar flow, providing rock-solid fuel pressure stability even under extreme demand.
