2/23/2024 0 Comments Fuel pressure regulator radium![]() This design has been tested to regulate over 1,200 liters per hour (see MORE DETAILS tab).ġ. See the installation instructions for more details. Furthermore, this added precision will resist diaphragm flutter and optimize pressure stability. This permits the DMR to be used with practically any horsepower engine. Two interchangeable orifices are included with calculated flow diameters to match the fuel pump flow to the regulator. Two 1/8" NPT plugs are provided.įuel pressure is dialed in using the preloaded set screw on top of the regulator. Unlike the previous generation, this DMR has two 1/8" NPT side port locations that can be used with a pressure gauge, transducer, temperature probe, etc. Other adapter fittings can be installed in the return port if needed (sold separately). The provided 90 degree 6AN male fuel return fitting (shown below) can swivel 360 degrees permitting a multitude of mounting configurations. The return port on the bottom is threaded for 6AN ORB. If mounting the regulator off-rail, other adapters can be screwed into this port on the regulator (sold separately HERE). Other swivel adapters will be made available in the future. A swiveling double ended adapter (shown below) is included with the kit that allows the regulator to be used in any compatible 8AN ORB fuel rail port, such as those found Radium Engineering fuel rails. ![]() The main inlet port on the regulator is female threaded for 6AN ORB. Return Orifices (silver orifice pre-installed) Swiveling Inlet Adapter Fitting (for 8AN ORB Fuel Rail) Fuel Pressure Regulator (Black or Green Top) Part numbers 20-0623-00/-01 include only the parts below. This regulator is safe to use with E85 and other alternative fuels. The compact size fits in areas with limited space, without sacrificing performance. It can be mounted directly to a compatible fuel rail port using the included 360 degree swiveling adapter, or mounted remotely away from the fuel rail. The Radium Direct Mount Regulator (DMR) is a compact high performance adjustable EFI fuel pressure regulator designed with a unique highly versatile mounting system. This secures to the front 1/8″-27 NPT port of the fuel pressure regulator housing.NEW FOR 2020! (Available in 8AN ORB only at this time) Radium also offers an optional fuel pressure gauge (shown below). If a significantly higher flowing pump is used, the minimum pressure ratings may be higher than what is advertised. If installing in a ~600hp+ engine, consider our adjustable high flow fuel pressure regulators. Radium FPRs are tested using a common high flowing Walbro 255lph pump. NOTE: The exact min, static, and max pressures are influenced by the flow rate of the fuel pump being used. Radium provides 2 different GENUINE Bosch regulator tops: 3.0 Bar (43.5 psi) static and 4.0 Bar (58.2 psi) static. This option includes everything needed with the exception of the regulator top, as shown below. If one of these is required, select Radium 20-0014. ![]() Also, there are unique non adjustable Bosch variations that are available, such as 3.5 Bar. There are aftermarket adjustable regulator tops that will snap into the Radium billet housing. Anodized Aluminum Mounting Bracket OPTIONS NOTE: The 3 and 4 Bar Bosch regulator tops are NOT adjustable.Įach regulator body is laser etched and anodized for a superior finish. There is also a 1/8NPT female port for a guage or pressure transducer. The main ports are -6AN O-Ring (9/16-18 female thread) and will accept a variety of adapter fittings. This reduces the number of fittings required and eliminates a possible leak point. The compact housing is equipped with an integrated machined -6AN flare fitting for the return port on the bottom. Or if the vacuum reference is removed a constant static fuel pressure can be achieved. As intake manifold pressure changes, the fuel pressure changes at the same rate. The Bosch regulator tops are vacuum referenced with a 1:1 ratio. The regulator body is held in the housing with a stainless steel snap ring and it can easily be removed for cleaning or replacement using a pair of snap-ring pliers. The extremely compact billet aluminum housing provides a convenient package for plumbing and mounting. These Bosch regulator units are the same found on millions of OEM vehicles from Porsche, Audi and VW to Ford so the build quality is extremely high. The universal Radium Fuel Pressure Regulator (FPR) is built around an OEM Bosch regulator top.
