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.
However, 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 its 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.
INCLUDED IN THE MPR KIT:
-Mounting bracket with hardware
-Interchangeable return orifices
-6AN ORB plug (x2)
-8AN ORB plug (x1)
-6AN male adapter (x3)
-8AN male adapter (x1)
If the fuel pressure gauge and O-ring adapter P/N: 20-0121 is selected, the 3/4"-16 (-8AN) port can no longer be used.
Alternatively, this gauge adapter HERE can be used on one of the -6AN ports.
