Fuel tank, as from model 1971
As from model 1971 the fuel tank is designed so as to
allow internal expansion of the fuel. The expansion space
is opened by a valve which is actuated by the filler cap.
Fuel tank ventilation
When fuel is poured in, the tank (1) will not be complete-
Iy filled, and instead the level rises only slightly above
the lower opening on the venting tube The reason
for this is that an air cushion is formed above this level
and prevents further filling of the tank.
The formation of this air cushion is due to the fact that
a Spring-loaded valve (5) located in the filler pipe (2)
blocks the upper opening on the venting tube (4) from
the upper side of the tank.
When the tank cap (7) is screwed on, a lever is actuated
which opens the valve, thus providing a communication
from the upper part of the tank to the surrounding air
via the ventilation hose (6) which runs out under the rear
fender. The fuel, which increases in volume when the
temperature rises, is now able to expand inside the tank
instead of being pressed up through the filler pipe As
the fuel level becomes lower in course of driving, air is
drawn into the tank via the ventilation hose
