OVERVIEW
A remote mounted fuel filler is NOT located directly on the fuel tank or fuel cell, but rather somewhere else on the vehicle, such as the fender. It is made up of 3 main components:
1. Remote filler. This is the filler housing and cap that attaches to the exterior of the vehicle.
2. Remote fill neck. This is the barbed or AN connection that attaches to the FCST or fuel cell.
3. Filler hose. This is the black or clear hose attaching #1 and #2 on this list.
PRODUCT VIDEO
COMPONENT 1: REMOTE FILLER
Choose from 3 styles of remote filler caps:
- Standard filler cap: This is a threaded fuel cap that is vented and has roll-over protection if the vehicle ever becomes inverted.
- Swing valve filler: This capless filler mimics modern OEM fillers and swings open when a filler nozzle is inserted. Nothing has to be unscrewed.
- Dry break filler: This quick-fill system mates to our 1.5" quick fill dry break dump cans for fast filling without spills.
Choose from 3 styles of remote fill hose attachment points:
- 1.5" Barb: This is a compact 1.5" barb, angled straight.
- 1.5" Elbow: This elbow attaches at a 75° angle and can rotate to point any direction. The elbow can be removed to attach a 24AN filler hose.
- 2.25" Barb: This is a compact 2.25" barb, angled straight.
COMPONENT 2: REMOTE FILL NECK
Choose from 2 styles of fill necks: The first is a simple straight barb, while the other is a 75° bent elbow that can be clocked any direction, or removed to attach a 24AN filler hose. The third option shown in the photos below is also a simple straight barb, but is 6-bolt and applies only to the discontinued FCST. Current versions of the FCST-X are all 3-bolt flanges.
COMPONENT 3: FILLER HOSE
1.5" filler hoses are available in black and in clear. When choosing, remember that the clear hose is not reinforced and the black hose is. This means that the clear hose does not bend well without kinking. The black hose can bend quite well.
SPECS & FEATURES
20-1003 REMOTE MOUNT, SWING VALVE FILLER, 1.5IN
The fuel filler typically secures to the vehicle body. The fuel cap swings open like an OEM "capless" fuel filler. Nothing has to be unscrewed. The swing valve seals using an FKM O-ring. Furthermore, a press-fit dust cap tethers from the flange mount for quick access. The 30mm opening is large enough for both gasoline and diesel fill nozzles.
The fill neck has a machined hose barb connection for 1.5in filler hose (available HERE). The outer diameter is 4.75in and uses 4.25in P.C.D for the five M5 bolts. Total height is 4.1in. Requires a 77mm (3.03in) hole to be fabricated. The o-ring sealed 1.5in barbed outlet is interchangeable. By simply removing 6 screws, a different outlet adapter (sold separately) can be installed. If needed, a tether is also provided, as shown below.
NOTES
- Uses the same threads as the dry break and the standard fill cap. They are all interchangeable.
- Does not include accessories to connect to the fuel tank.
- Can be upgraded later to a dry break using Radium 20-0549-V.
