Radium Engineering 20-0527 Remote Mount Fill Neck Straight 1.5in Barb FCST

Vehicle Fitment

• Universal fit - compatible with any Radium Engineering Fuel Cell Surge Tank (FCST) system or custom fuel system build requiring a remotely mounted straight fill neck with a 1.5 in. ID fill hose connection
• Suitable for any vehicle or motorsport application where the fuel surge tank filler point must be relocated away from the tank body for accessibility or packaging reasons

Fitment Notes

• Straight fill neck orientation - for angled or 90-degree neck configurations, see other fill neck options in the Radium FCST accessory lineup
• Designed for use with 1.5 in. ID fill hose - verify your fill hose inner diameter matches before ordering
• Intended for Radium Fuel Cell Surge Tank (FCST) systems - allows the filler cap to be remotely positioned for easier access in tight engine bays or custom chassis applications
• Integrated check valve flapper prevents fuel from flowing backward out of the tank during filling - maintains fuel system pressure and prevents spillage
• Installation instructions available at radiumauto.com

Features

• Integrated check valve flapper allows fuel to flow in during filling but prevents backflow - eliminates the need for a separate check valve in the fill line
• Straight neck orientation provides a clean, low-profile fill point when mounted in-line with the fill hose run

Product Description

The Radium Engineering 20-0527 is a straight remote mount fill neck with an integrated check valve flapper, designed for use with Radium Fuel Cell Surge Tank (FCST) systems and custom fuel system builds requiring a remotely positioned fuel filler point. The straight orientation keeps installation clean and low-profile when the fill neck is run in-line with the hose. The 1.5 in. barb connects to standard 1.5 in. ID fuel-compatible fill hose, and the built-in check valve prevents backflow during and after filling. CNC machined aluminum construction is compatible with all fuel types including E85 and methanol. Universal fit - suitable for any vehicle or application using a Radium FCST or requiring a remote-mount fuel fill point.

For angled or 90-degree remote fill neck configurations, see other fill neck options in Radium's FCST accessory catalog. Installation instructions available at radiumauto.com.
