Radium Engineering Fuel Pressure Regulator – Bosch Top Style

This universal Radium Engineering fuel pressure regulator (FPR) is built to house OEM Bosch regulator inserts and offers a clean, compact package for integrating into custom fuel systems. Suitable for a wide variety of vehicles, the included fittings and mounting hardware make for a simple and secure installation.

Vehicle Compatibility (with Bosch Insert):

• Audi 1.8L Turbo

• Ford Falcon BA / BF / FG XR6 Turbo

• Ford Territory Turbo

• FPV F6 Typhoon Turbo

• Volkswagen 1.8L Turbo

• And many more using Bosch-style regulators

Overview:
Radium’s billet aluminum FPR housing is designed to securely hold Bosch OEM-style regulators. Two genuine Bosch tops are available: 3.0 Bar (43.5psi) and 4.0 Bar (58.2psi), both offering a 1:1 vacuum reference. These regulators are not adjustable, making them ideal for OEM replacements or setups that require consistent static pressures.

The housing includes two 6AN ORB ports for inlet/outlet, a 1/8" NPT port for a gauge or sensor, and an integrated -6AN male return port. The assembly is anodized for corrosion resistance and laser-etched for a professional finish.
