Radium Engineering Fuel Pressure Regulators with Pulse Damper

Radium Engineering fuel pressure regulator with pulse dampers are the ultimate solution for consolidating critical fuel system components into a high-flow package. It is a fully functional high performance pressure regulator with a unique built-in fuel pulse damper—an industry first!

Fuel pressure regulator with pulse damper features:

* Compatible with all gasoline and alcohol blends of fuel including E85
* Fuel pressure is dialed in using the preload set screw on top—unlike many others, the stainless steel adjustment screw has super fine threads for resisting vacuum/boost leaks and fine tuning fuel pressure
* Two interchangeable orifices are included to match the amount of fuel bypassed for the application—this added precision will resist diaphragm flutter and optimize pressure stability
* With the addition of interchangeable return orifices, the fuel pressure regulator-damper is a good match for big to small, powered engines
* The integrated fuel pulse damper stabilizes fuel pressure created by the fuel pressure regulator, fuel pump, fuel injectors, etc.—base pressure is measured with the fuel pump running without a vacuum line connected to the regulator
* The inlet (side) port and outlet (bottom) port feature large 10AN ORB (7/8 in. to 14) threaded ports—two -6AN and two -8AN adapter fittings are included to suit most aftermarket fuel systems
* When installing, the O-rings require petroleum oil for lubrication
* The 1/8 in. NPT auxiliary port can be used for monitoring fuel pressure, temperature, etc.
* Mounting—the FPR-D assembly features two M6x1mm threaded mounting holes—a laser-cut anodized aluminum mounting plate with countersink M6x1mm bolts/nuts are included
* The FPR-D can be mounted any direction including upside down

What's included:

* Fuel pressure regulator-damper
* Aluminum mounting bracket
* Aluminum 6AN male adapter (x2)
* Aluminum 8AN male adapter (x2)
* Aluminum 1/8 in. NPT port plug
* Interchangeable return orifices
* M6x1mm mounting hardware
* Boost referenced Y-adapter
* Vacuum Hose, 3/32 in. I.D.

Note: Not recommended for the low pressure side of mechanical fuel pumps. Not intended to be used directly on a fuel rail port.
