Description
Radium Engineering 20-1103 Remote Mount Swing Valve Filler - 1.5in Elbow
Application: Universal – remote-mount fuel filler for fuel cells and surge tanks
Part Type: Remote mount fuel filler – swing valve, 1.5in 24AN elbow
Part Number: 20-1103
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 20-1103 uses an OEM-style capless swing valve, so there is no cap to unscrew when refuelling, with a 75° 24AN elbow outlet for 1.5in filler hose.
The 30mm filler opening is large enough for both petrol and diesel nozzles, the swing valve seals with an FKM O-ring, and a press-fit dust cap is tethered to the flange. The filler can later be upgraded to a dry break with the Radium 20-0549-V.
Key Features
- Capless Swing Valve: OEM-style design – no unscrewing required to refuel
- 30mm Opening: Large enough for petrol and diesel nozzles
- 24AN Elbow Outlet: 1.5in, 75° 24AN elbow for 1.5in filler hose
- Tethered Dust Cap: Press-fit dust cap tethered to the flange
- Flush Remote Mount: 120.7mm (4.75in) flange with five M5 bolts on a 108mm (4.25in) PCD; requires a 77mm (3.03in) mounting hole
- Interchangeable Caps: All Radium remote filler cap styles share the same threads and are interchangeable
- Swappable Outlet: The outlet adapter can be changed by removing six screws (adapters sold separately)
