Venturi Jet Pump Kit

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.

Pump Outlet Adapter, Check Valve

This 6AN male adapter is used to integrate a high flow check valve on the outlet of many fuel pumps. The valve outflows the integrated check valve that comes standard on many fuel pump outlets. Furthermore, decreasing this restriction allows the pump to operate at less current.

Lotus Fuel Rail Hose Kit For Fuel Pump Adapter

This kit is for the Lotus with the 2ZZ-GE engine ONLY.

The kit includes a 40" long PTFE hose with black PCV cover, a SAE quick disconnect adapter (for the OEM rail), a rubber firewall grommet, and a SAE fuel hose removal tool

Fuel Pulse Damper, OEM Style

The opening and closing of the injectors create pulses in the fuel rail, which can lead to unstable fuel pressure. This damper should be used (especially with high flow injectors) in order to achieve a safe and consistent rail pressure. The internal diaphragm will absorb oscillations and smooth fuel pressure.

 6AN ORB high pressure female ports (in/out). 6AN male male low pressure return port. 1/8" NPT female port.
