Product Description

The Radium Engineering 20-1047 Remote Mount Fill Neck is a universal accessory for advanced fuel systems, designed specifically to interface with Radium FCST-X style fuel cell surge tanks. Featuring a 75° 24AN hose end and a 1.5" barb outlet, this fill neck allows flexible plumbing of remote filler hose away from the fuel cell or surge tank area. It is ideal for race cars, custom fuel systems, and fabricated fuel compartments where traditional filler necks are impractical.

The included FKM O-ring flange and stainless hardware provide a secure, leak-resistant connection at the surge tank fill plate, while the specialized aluminum wrench helps install and tighten the 24AN hose end without damage. Designed to work with high-performance and motorsport fuel systems, the 20-1047 Fill Neck accommodates a wide variety of hose routing configurations when paired with appropriate fuel hose and remote body-mounted filler options.
