Full Description:
The Multi Pump Regulator (MPR) is the ultimate solution for simple or complex high-flow fuel systems. It's unique port configuration makes it ideal for combining multiple fuel pumps into a single feed line or vice versa. It can also be used for single pump applications by simply plugging the unused ports.

The MPR can be plumbed many different ways to suit most any installation; traditional flow-through or dead-end systems. Because of this flexibility, it is also perfect for Radium fuel systems by eliminating the need for an extra "Y" fitting. The lower 2 opposing return ports are unique in that they flow parallel with the pressure ports eliminating the need for elbow fittings. Either lower port can be used for the return line, just plug the one not used (a plug is included).

At the time of it's release this regulator was the only one on the market that could be floor mounted. 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.

Two interchangeable orifices are included to match the amount of fuel bypassed for the application. Furthermore, this added precision will resist diaphragm flutter and optimize pressure stability.
See the installation instructions for more details.

The 1:1 vacuum reference high flow design has been tested to regulate over 1,400 liters per hour. Furthermore, with the addition of interchangeable return orifices, the regulator is good match for stock street car, or highly modified drag racer! It is compatible with all gasoline and ethanol blends of fuel. Fuel pressure is dialed in using the preload set screw on top.

Includes:
• Multi-Pump Regulator
• Mounting Bracket with Hardware
• Interchangeable Return Orifices
• 6AN Orb Plug (x2)
• 8AN Orb Plug (x1)
• 6AN Male Adapter (x3)
• 8AN Male Adapter (x1)

Radium MPR Minumum Fuel Pressure:
The graph shows the minimum fuel pressure the regulator can achieve as a function of pump flow rate. This test was performed with the adjustment screw completely backed out, no preload.

For example, if you have two pumps that flow 320LPH (total 640LPH), the approximate minimum pressure the regulator can achieve is about 23.5 psi. Note: if an OEM fuel pressure regulator is used for 640LPH, it will likely not be able to bypass enough fuel.

With the Radium MPR, simply spin the set screw clockwise to achieve higher pressures. Note: Most EFI systems operate at 43.5 psi (3Bar) static fuel pressure.See more Radium Products
