Radium Engineering
Radium Engineering's venturi jet pump (Radium 20-0180) moves fuel from one side of a tank to the other: fuel flowing through the venturi creates vacuum at the perpendicular port. Factory jet pumps are sized for stock pump flow and become a restriction, and a cause of high fuel pressure, once a higher-flow pump is fitted. Radium's version is built for high-flow aftermarket pumps and comes with three interchangeable orifices, calculated and vacuum-tested across pump combinations.
