Description
Radium Venturi Jet Pump Kit
Application: Universal – saddle-style fuel tanks (RWD / AWD) with high-flow aftermarket pumps
Part Type: Venturi jet pump kit
Part Number: 20-0180
The Radium Venturi Jet Pump is an effective device for drawing fuel from one side of a saddle-style fuel tank to the other. Fuel flowing through the venturi creates vacuum in the perpendicular port, transferring fuel across the tank.
OEM jet pumps are designed for factory pump flow rates – with a higher-flowing aftermarket pump they become a major restriction in the return line and cause high fuel pressure, and drilling them out compromises their function. The Radium jet pump is designed for high-flow aftermarket pumps and includes three orifice sizes, calculated and vacuum-tested with multiple pump combinations. The machined aluminium housing is anodised and laser engraved.
Key Features
- High-Flow Design: Made for aftermarket pump flow rates without excess return restriction
- Three Orifice Sizes: 0.75mm, 3mm and 3.5mm, vacuum-tested with multiple pumps
- Universal Barbs: 8.5mm barbs suit 5/16" or 3/8" ID hose
- 6AN ORB Siphon Port: Accepts any 6AN ORB fitting
- Billet Housing: Machined aluminium, anodised and laser engraved
What's Included
- 1x Venturi jet pump
- 1x 6AN ORB to 8.5mm barb siphon port fitting
- 1x 0.75mm inlet orifice fitting
- 1x 3mm inlet orifice fitting
- 1x 3.5mm inlet orifice fitting
Optional Parts
- Radium Duckbill Valve (18-0026) – fits directly to the outlet barb in place of a submerged hose
Important Notes
- The OEM venturi jet pump must be removed – the system will not work if fuel is pushed through the OEM unit
- A hose (not included) should be fitted to the 8.5mm outlet barb with its end submerged at a low point in the tank, to stop the jet pump drawing air in the opposite direction
- Barbs suit 5/16" or 3/8" ID hose – rigid hose needs a small ID to seal
- The siphon port fitting can be swapped for any 6AN ORB fitting
- Installation instructions are available in the Instructions tab
