Fuel Tank Cap; Filling The Fuel Tank - Triumph Bonneville Handbook

General Information

Fuel Tank Cap

1 Fuel Tank Cap
To open the fuel tank cap, rotate the cap
counter-clockwise and lift clear of the tank
filler neck.
To close the cap, align the cap to the tank
filler neck and rotate the cap clockwise until
the cap seals against the filler neck. In the
fully closed position, a ratchet mechanism
prevents over-tightening of the cap by
allowing the outer part of the cap to turn
independently of the internal part.

Filling The Fuel Tank

Avoid filling the tank in rainy or dusty
conditions where airborne material can
contaminate the fuel.
Caution
Contaminated fuel may cause damage to
fuel system components.
Fill the fuel tank slowly to help prevent
spillage. Do not fill the tank to a level above
the bottom of the filler neck. This will ensure
there is enough air space to allow for fuel
expansion if the fuel inside the tank expands
through absorption of heat from the engine
or from direct sunlight.
