If the fuel pressure gauge and O-ring adapter P/N: 14-0119 is selected, the 3/4"-16 (-8AN) port can no longer be used.Īlternatively, this gauge adapter HERE can be used on one of the -6AN ports. The fuel rail mounts using the OEM studs, nuts, and insulating spacers. The kit is compatible with all fuel types including popular alcohol mixtures such as E85. Furthermore, a Radium FPD-R, 8AN ORB fuel pulse damper can be installed (shown in top port). Furthermore, with the addition of interchangeable return orifices, the regulator is a good match for stock street cars or highly modified drag cars! It is compatible with all gasoline and alcohol blends of fuel including E85. Fuel pressure is dialed in using the preload set screw on top. A Radium DMR, 8AN ORB regulator (shown in the end port) can be used in place of the OEM FPR. The Fuel Pressure Regulator Damper-Rotating Assembly (FPRD-RA) is the ultimate solution for consolidating critical fuel system components into a high-flow. The 1:1 rising rate high flow design has been tested to regulate over 1,400 liters per hour (see MORE DETAILS tab). Furthermore, this added precision will resist diaphragm flutter and optimize pressure stability. Two interchangeable orifices are included to match the amount of fuel bypassed for the application.

Alternatively, wall mounting can be accomplished by not using the included mounting bracket and simply mounting using the holes that pass through the body, or by mounting the regulator sideways. FEATURES Multi-Port Regulator Mounting bracket with hardware Interchangeable return orifices 6AN ORB plug (x2) 8AN ORB plug (x1) 6AN male adapter (x3) 8AN. Either lower port can be used for the return line, just plug the one not used (a plug is included). The lower 2 opposing return ports are unique in that they flow parallel with the pressure ports eliminating the need for elbow fittings. The Radium Direct Mount Regulator-Rotating Assembly (DMR-RA) is a compact high performance adjustable EFI fuel pressure regulator. The MPR can be plumbed many different ways to suit most any installation traditional flow-through or dead head systems. Because of this flexibility, it is also perfect for Radium fuel systems by eliminating the need for an extra "Y" fitting. However, it can also be used for single pump or single fuel rail applications by simply plugging the unused ports. Alternatively, it can be used to split a single feed line to a dual bank fuel system with 2 fuel rails. ![]() Its unique port configuration makes it ideal for combining dual fuel pumps into a single feed line. 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.The Multi Port Regulator (MPR) is a great solution for both simple and complex high-flow fuel systems. These FPRs are tested using a common Walbro 255lph pump. NOTE: The exact min, static, and max pressures are influenced by the flow rate of the fuel pump being used. There is also a 1/8 NPT female port for a gauge, pressure transducer, etc. Each FPR housing is laser etched and anodized for a superior finish. ![]() The 6AN male return port is integrated into the housing. The two main high pressure ports are threaded for 6AN ORB. With the ability to support multiple pumps and fuel rails this regulator will maintain fuel pressure at idle during low fuel demand as well as at WOT making. The regulator top is secured with a stainless steel snap ring and can easily be removed using snap-ring pliers. The Radium Engineering Multi-Port Fuel Pressure Regulator (MPR) is manufactured in the USA and is the ultimate solution for any fuel system. The compact Radium Engineering billet aluminum FPR housing provides a convenient package for plumbing and mounting. ![]() These Bosch regulator tops are vacuum referenced with a 1:1 ratio and are NOT adjustable. These Bosch units are found in many applications, including:Īlternatively, Radium offers two GENUINE Bosch regulator tops: 3.0 Bar (43.5 psi) static and 4.0 Bar (58.2 psi) static. Radium Engineering Fuel Pressure Regulator (FPR) is built around the common OEM Bosch regulator inserts.
