Radium Engineering Fuel Pressure Regulator

This universal Radium Fuel Pressure Regulator (FPR) is built around the common OEM Bosch regulator tops found in many Audi/VW (and other) applications. The compact billet aluminum housing provides a convenient package for plumbing and mounting. The regulator body is held in the housing with a stainless steel snap ring and can easily be removed for cleaning or replacement using snap-ring pliers. The Bosch regulator tops are vacuum referenced with a 1:1 ratio. The two main high pressure ports are threaded for 6AN ORB. There is also a 1/8 NPT female port for a gauge, pressure transducer, etc. Each regulator body is laser etched and anodized for a superior finish. Radium offers two different GENUINE Bosch regulator tops: 3.0 Bar (43.5 psi) static and 4.0 Bar (58.2 psi) static. NOTE: The exact min, static, and max pressures are influenced by the flow rate of the fuel pump being used. These FPRs are tested using a common Walbro 255lph pump. If a higher flowing pump is used, the minimum pressure ratings may be higher than advertised. For applications with more pump flow, consider a high flow fuel pressure regulator. NOTE: The 3 and 4 Bar Bosch regulator tops are NOT adjustable.
