RADIUM Engineering 20-1100-00 Multi-Port Fuel Pressure Regulator MPR-RA

The RADIUM Engineering Multi-Port Regulator-Rotating Assembly (MPR-RA) is a premium solution engineered for both simple and complex high-flow fuel systems. This USA-manufactured universal adjustable fuel pressure regulator features a versatile port configuration that makes it ideal for combining dual fuel pumps into a single feed line, splitting a single feed line to dual bank fuel systems with two fuel rails, or operating with single pump applications by simply plugging unused ports.

Key Features:

• Tool-less pressure adjustment with incremental detents providing 1psi (+/-0.5psi) adjustment per click for precise tuning
• 360-degree swiveling vacuum reference port with double O-ring seal for 1:1 rising rate vacuum reference
• RA-series design with single stainless steel return orifice generating laminar flow for enhanced pressure stability
• Multiple port configuration: Two 6AN ORB (9/16"-18) feed ports, one 8AN ORB (3/4"-16) feed port, and two 6AN ORB return ports
• Minimum pressure: 18.5 psi (1.3 bar); ideal for pump flows from 200 lph to 1400 lph
• Compatible with all gasoline types including unleaded, leaded, oxygenated, pre-mixes, and alcohol blends (methanol, ethanol, E85)
• Black anodized finish for durability and professional appearance
• Flexible mounting options with M6 threaded holes for wall mounting or included bracket for floor mounting

Included Components:

• Multi-Port Regulator-Rotating Assembly body
• Mounting bracket with M6x1mm hardware
• Four interchangeable 10-32 threaded vacuum port fittings (barbed fitting, 3AN male fitting, push-to-connect fitting, vacuum plug)
• 6AN ORB port plugs (x2)
• 8AN ORB port plug (x1)
• 6AN male adapter fittings (x3)
• 8AN male adapter fitting (x1)

This regulator can be plumbed multiple ways to suit various installations including traditional flow-through or dead-head systems, eliminating the need for additional Y-fittings. The MPR-RA is the updated replacement design for discontinued part numbers 20-0100-00 and 20-0100-01, offering refined pressure management based on years of track and bench testing data.
