FLRT
See Figure 1. The fuel filler cap is on the right side of the fuel tank.
The cap on the left side is the fuel gauge. The fuel gauge is not removable.
FLHTCUTG
The fuel filler cap is beneath a pushbutton or locking door on the fuel tank.
Pushbutton fuel door: See Figure 2. Press the pushbutton to release the door.
Locking fuel door: See Figure 3. Unlock fuel door with the ignition key. Lock fuel door by removing key and closing fuel door.
Fuel Filler Cap
Remove: Turn fuel filler cap counterclockwise to remove.
Fill fuel tank slowly to prevent fuel spillage. Do not fill above the bottom of the filler neck insert. Leave enough air space to allow for fuel expansion. Expansion can cause an overfilled tank to overflow fuel through the filler cap vent onto surrounding areas.
Install: Turn fuel filler cap clockwise until it clicks. The ratchet action of the cap prevents over-tightening.
