Radium 20-0180 Venturi Jet Pump Kits

OVERVIEW

The Radium Engineering Jet Pump is an effective device for drawing fuel from one side of a fuel tank to the other. Fuel flowing through the venturi creates vacuum in the perpendicular port. The effectiveness of this vacuum is demonstrated in the video above.

OEM jet pumps are commonly found in vehicles with saddle-style fuel tanks (RWD or AWD drivetrains) and are designed for factory fuel pump flow rates. When a higher flowing pump is installed, the factory jet pumps becomes a major restriction in the return line causing high fuel pressure. In some cases drilling out the OEM jet pump can relieve the pressure, but the function of the jet pump is then compromised. The Radium Engineering Jet Pump is designed for high flow aftermarket pumps and includes different venturi orifices to match a wide range of pump flow rates.

The Radium Venturi Jet Pump uses a machined aluminum housing that is anodized and laser engraved. The kit includes 3 interchangeable orifices that were precisely calculated and vacuum pressure tested with multiple pump combinations. Consult the installation instructions for additional details on installation and use.

All 3 hose barbs connections are compatible with 5/16" or 3/8" ID hose. Also, the crossover siphon port can be easily adapted to common hoses as it uses 6AN ORB (9/16-18 O-ring) female threads.
