Radium Engineering Bosch Fuel Pressure Regulator

This Radium Engineering Bosch Fuel Pressure Regulator is built around an OEM Bosch regulator top which are the same as found on millions of OEM cars such as Audi, Ford, Porsche & VW, so the build quality is to an extremely high standard.

There are aftermarket adjustable regulator tops that will snap into the Radium billet housing as well as the unique non adjustable Bosch variations that are available, such as the provided 3 or 4BAR regulator tops.

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.

Available with or without an regulator pressure top.

Product Description
Details

This Radium Engineering Bosch Fuel Pressure Regulator is built around an OEM Bosch regulator top which are the same as found on millions of OEM cars such as Audi, Ford, Porsche & VW, so the build quality is to an extremely high standard.

There are aftermarket adjustable regulator tops that will snap into the Radium billet housing as well as the unique non adjustable Bosch variations that are available, such as the provided 3 or 4BAR regulator tops.

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.

Radium provides 2 different genuine Bosch regulator tops, a 3BAR (43.5PSI) static and a 4BAR (58.2PSI) static. The exact minimum, static, and max pressures are influenced by the flow rate of the fuel pump being used. Radium FPRs are tested using a common high flowing Walbro 255lph pump. If a significantly higher flowing pump is used, the minimum pressure ratings may be higher than what is advertised. If installing in a 600hp+ engine, then consider a Radium Engineering adjustable high flow pressure regulator.

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 adaptor fittings. There is also a 1/8NPT female port for a gauge or pressure transducer.

The extremely compact billet aluminium 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.

Available with or without an regulator pressure top.
