Radium 20-1841-03 Complete Refueling Kit for FCST-X Remote 1.5in. Dry Break

Vehicle Fitment

• Universal - Compatible with Radium Engineering FCST-X Fuel Cell Surge Tank only

Fitment Notes

• Not compatible with older Radium Fuel Cell Surge Tanks (non-X FCST) that use a 6-bolt filler neck
• Designed for vehicles that require a quick-fill dry break filler mounted remotely from the fuel cell, such as a body panel-mounted receiver
• Sold as a complete kit - no additional filler, vent, or dump can components need to be sourced separately

Features

• Dry break remote filler enables quick-disconnect, spill-resistant fueling
• 5-gallon dump can features a dry break probe for fast, secure fuel transfer
• 1.5 in. remote fill hose connects the receiver to the FCST-X-mounted fill neck elbow
• Included Dynamic Safety Valve (DSV) helps manage fuel flow and pressure during filling
• 12AN vent line ensures adequate airflow for fast, consistent filling without vapor lock
• Remote-mount receiver typically bolts to a body panel, keeping the fill point away from the tank itself - ideal for race car packaging
• Purpose-built to integrate directly with the Radium FCST-X's standard mounting points

Product Description

The Radium 20-1841-03 is a complete refueling kit built specifically for the Radium FCST-X fuel cell surge tank, designed for racing applications that need a quick-fill dry break filler mounted remotely from the tank itself. Rather than sourcing a filler, vent kit, and dump can separately, this kit bundles everything needed for a fast, spill-resistant refueling setup in one package.

A dry break remote filler receiver typically mounts to a body panel away from the fuel cell, with a 1.5-inch fill hose running to the FCST-X-mounted fill neck elbow for a secure, high-flow connection. The included 5-gallon dump can uses a matching dry break probe, so fueling is a simple connect-and-pour operation rather than wrestling with a traditional cap and funnel. A 12AN vent line and Dynamic Safety Valve work together to manage airflow and fuel pressure during filling, helping keep fill times fast and consistent under race conditions.

This kit is compatible with the current FCST-X only - older Radium fuel cell surge tanks with a 6-bolt filler neck use a different set of refueling parts, so confirm which surge tank generation you're running before ordering.
