Capacity: 60 дм³.

Arrangement of a mouth of a tank: on the right back wing.

Fuel type: этилированный with октановым number 98 or неэтилированный with октановым number a minimum 95, however at its use the ignition advancing on 4 ° is necessary to reduce gasoline necessarily, and also in all engines 1,3 дм³ (type JCT) and in other, made till October, 1984, it is obligatory to refuel every fourth refuelling этилированными gasoline; engines 1,6 дм³ and 2,0 дм³, let out since November, 1984 are adapted for use неэтилированного gasoline.

THE FUEL PUMP

Mechanical диафрагменный the pump is put in action by the clown of an intermediate shaft.

Pressure of giving of fuel: 24 – 38 кПа.

THE AIR FILTER

The air filter has the replaced paper filtering element located in the case from an artificial material.

Replaced element air фильтра:марка: Motorcraft, type: 71 HF 9601 BB.

THE CARBURETTOR

In engines 1,3 дм³ and 1,6 дм³: carburettor Ford (Motorcraft) with changeable section диффузора, with the automatic starting arrangement and the accelerating pump, result in action by vacuum in an inlet collector.

In engines 2,0 дм³: two-chamber consecutive carburettor Weber, with the automatic starting arrangement and the accelerating pump put in action by a mechanical way.
