Fuel system
The fuel tank is located above the rear axle behind the par-
tition between the passenger compartment and the luggage
compartment. The fuel tank capacity is 15.8 US gals. (60
lit.).
The tank cap has no ventilation hole. Ventilation takes
place via a hose from the filler pipe. This hose runs out
under the rear fender (model 1970).
As from model 1971 the fuel system is equipped with
an evaporative loss control unit. This unit includes a
charcoal canister which is placed in the engine compart-
ment. It absorbs the vapor from the tank when the en-
gine is not running. The charcoal is purged when the en-
gine is running. This is achieved by fresh air which is
sucked through the filter in the bottom of the canister
and further to the carburetor.
The fuel filter and the canister filter should be renewed
at intervals according to the directions given in the Service
Book (up to and incl. model 1972). As from model 1973,
see maintenance program in the Owner's Manual.
The fuel pump, which is of diaphragm type, pumps the
fuel from the tank to the carburetor.
The Sonett III engine features a down-draft carburetor of
the FoMoCo make (Auto-Lite). The carburetor is similar
to the type fitted in Saab V4 engines, except that it fea-
tures a bigger main jet.
