Removing the Fuel Filler Cap
WARNINGDo not use aftermarket fuel caps. Aftermarket fuel caps may fit improperly and leak, which could lead to death or serious injury. See a Harley-Davidson dealer for approved fuel caps. (00034a)
FLHP: See Figure 1. Fuel filler cap is on the right side of the fuel tank. The cap on the left side is the fuel gauge and is not removable.
FLHTP: See Figure 2. Fuel filler cap is located beneath a pushbutton or locking door on the fuel tank.
- Push button fuel door: Push button to release the door. Tighten the fuel filler cap before closing the fuel door.
- Locking fuel door: Use the ignition key to unlock fuel door. Tighten the fuel filler cap before closing the fuel door.
To open, turn fuel filler cap counterclockwise and lift. To close, turn fuel filler cap clockwise until it clicks. The ratchet action of the cap prevents over-tightening. Fuel filler cap turns approximately three-quarters of a turn before it starts unscrewing.

Filling the Tank
WARNINGAvoid spills. Slowly open fuel filler cap. Do not fill above bottom of filler neck insert, leaving air space for fuel expansion. Secure filler cap after refueling. Gasoline is extremely flammable and highly explosive, which could result in death or serious injury. (00028b)
WARNINGDo not store motorcycle with gasoline in tank within the home or garage where open flames, pilot lights, sparks or electric motors are present. Gasoline is extremely flammable and highly explosive, which could result in death or serious injury. (00003a)
NOTICE
Do not spill fuel onto the motorcycle while refueling. Immediately wipe up fuel spills on your motorcycle. Fuel can cause damage to cosmetic surfaces. (00147b)
NOTICE
Use only unleaded fuel in catalytic converter-equipped motorcycles. Using leaded fuel will damage the emission control system. (00150c)
See Figure 3. Do not overfill the fuel tank. Insert the pump nozzle into the filler hole. Do not fill the tank beyond the bottom of the filler neck. A warm engine, the sun or extreme temperatures can cause the fuel to expand. Fuel can spill out of the tank and damage the finish. See Safety First → Safe Operating Rules.
