Product Description

The Radium 20-0180 Universal Venturi Fuel Jet Pump Kit is engineered to improve fuel movement inside saddle-style fuel tanks, especially when higher-flow aftermarket pumps are used. By using the venturi effect, fuel flowing through the pump creates a vacuum at a perpendicular port, drawing fuel from the opposite side of the tank to help balance pickup and reduce return line pressure. This design helps maintain steady fuel delivery under demanding conditions, such as aggressive driving or racing applications.

Constructed with a machined aluminum housing and anodized finish, the kit includes three different venturi orifices that can be swapped to match a range of pump flow rates and system needs. Hose barb connections support common 5/16" or 3/8" inner diameter hoses, and the siphon port uses a 6AN ORB interface for versatile plumbing options. It's ideal for custom fuel system builders and performance enthusiasts looking to eliminate factory jet pump restrictions in fuel tanks with saddle designs, such as those found on many rear-wheel-drive and all-wheel-drive platforms.
