Radium Engineering Duckbill Valve | Universal (18-0026)

The quietest part in a Radium hanger is a rubber valve doing one-way duty every second the engine runs.

The Radium Engineering Duckbill Valve is the replacement one-way valve used in Radium fuel pump hangers and surge tank assemblies: a fluorosilicone check element that lets return and transfer fuel flow one direction while blocking backflow, keeping collector reservoirs full and pickups submerged. It is a service part, sold individually, for rebuilds and refreshes of Radium in-tank hardware.

What You'll Feel

• Collector and reservoir function restored on a high-mileage hanger
• Original-spec one-way behavior, since this is the part Radium builds with
• A cheap line item that protects the expensive one: consistent fuel pickup

Features

• Fluorosilicone duckbill one-way valve
• Compatible with all fuel types including gasoline and E85
• Service replacement for Radium fuel pump hangers and surge tank assemblies using duckbill check valves

The Details

Duckbill valves earn their place through simplicity: two soft lips open under forward flow and press shut against reverse flow, with no spring, seat, or plunger to stick, and fluorosilicone keeps the lips supple through years of fuel immersion including alcohol blends. In Radium hangers the valve typically manages return flow into the collector, part of the architecture that keeps pumps fed during hard cornering, so a valve that has stiffened or torn shows up as the starvation behavior the hanger was bought to prevent. If a teardown reveals a tired valve, this is the correct refresh. Verify your assembly uses a duckbill valve before ordering.
