The universal Radium Fuel Pressure Regulator (FPR) is built around an OEM Bosch
regulator top. These Bosch regulator units are the same found on millions of OEM
vehicles from Audi and VW to Ford so the build quality is extremely high. The
extremely compact billet aluminum housing provides a convenient package for
plumbing and mounting. The regulator body is held in the housing with a
stainless steel snap ring and it can easily be removed for cleaning or
replacement using a pair of snap-ring pliers.
The Bosch regulator tops are vacuum referenced with a 1:1 ratio. As intake
manifold pressure changes, the fuel pressure changes at the same rate. Or if the
vacuum reference is removed a constant static fuel pressure can be achieved. The
compact housing is equipped with an integrated machined -6AN flare fitting for
the return port on the bottom. This reduces the number of fittings required and
eliminates a possible leak point. The main ports are -6AN O-Ring (9/16-18 female
thread) and will accept a variety of adapter fittings. There is also a 1/8NPT
female port for a guage or pressure transducer.
Each regulator body is laser etched and anodized for a superior finish.
