Description
Radium 20-1105-V Remote Mount, Vented Standard Filler, 1.5in Elbow
Application: Universal – remote-mount fuel filler for fuel cells and surge tanks
Part Type: Remote mount fuel filler – vented standard cap, 1.5in 24AN elbow
Part Number: 20-1105-V
A remote mount fuel filler sits away from the fuel cell or tank – usually on a body panel – and connects to the fill neck via filler hose. The Radium Engineering 20-1105-V uses a vented, threaded standard cap with built-in roll-over protection, and a 75° 24AN elbow outlet for 1.5in filler hose.
The cap is tethered to the filler, and the standard filler can later be upgraded to a dry break with the Radium 20-0549-V.
