Fuel tank device

Fuel tank 16 (see fig. 39) stamped, welded from two steel sheets. To improve corrosion resistance, the tank is leaded on both sides. The fuel tanks of the cars in question are interchangeable, have a capacity of 43 liters, including a fuel reserve.

The tank is installed under the body floor and fastened with two clamps 17 to the body brackets. Rubber gaskets are placed under the clamps. The filling pipe 14 is brought out into a niche in the right rear fender and is closed with a sealed plastic plug 12. The plug has a tightening torque limiter: on some cars, a lock can be installed in the plug. The filler neck is connected to the tank pipe with a hose made of petrol-resistant rubber. To prevent leakage of fuel during refueling, the upper part of the filling pipe is connected to the tank branch pipe by hose 15, through which air is displaced during refueling. The inner end of the pipe in the tank is located at a certain level, as a result of which the filling of the tank with fuel stops when the fuel level reaches the inner end of the pipe. There is a non-return valve inside the filling pipe to prevent fuel from escaping. To increase rigidity and reduce the possibility of fuel fluctuations when the car is moving, the tank has two partitions. Between the baffles is the float of the fuel gauge. Gauge 9 of the pointer assembly with a fuel receiving tube and a fuel drain tube is attached to the tank through a gasket. The fuel pickup tube has a strainer.

Two drainage tubes are installed in the fuel tank, inserted one into the other and having a common outlet into the branch pipe, which is connected to the gasoline vapor separator 10. Separator capacity 3 l. Gasoline vapors, condensing in the separator, merge back into the tank. The ends of the drain tubes in the tank are located on the right and left sides in order to prevent fuel leakage during crepes and turns of the car.
