Radium Engineering Multi-Pump Fuel Pressure Regulator - Black Top

The Multi Pump Regulator (MPR) is manufactured in the USA and is the ultimate solution for simple or complex high-flow fuel systems. It's unique port configuration make it ideal for combining multiple fuel pumps into a single feed line or vice versa. 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 surge tanks 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. Furthermore, the MPR is the only regulator on the market that can 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.

Fuel pressure is dialed in using the preload set screw on top. The 1:1 vacuum reference high flow design has been tested to regulate over 1,400 liters per hour (see MORE DETAILS tab). Furthermore, with the addition of interchangeable return orifices, the MPR can be used in ANY horsepower output EFI system imagineable and is compatible with all gasoline and ethanol blends of fuel.
