Fuel tank
Made of stamped sheet metal and installed in front of the rear axle of the car. Tank capacity: 40 l.
Fuel pump
The mechanical diaphragm pump is driven by the camshaft eccentric. The pump housing is crimped and only the filter is replaced. Fuel supply pressure: 22–35 kPa.
Air filter
Dry with filter element Motorcraft EFA 248.
Thermoregulator
Temperature of opening of the thermostat flap with carburetor: 28±2°C.
Motorcraft VV Carburetor
The carburetor is vertical, with an automatic air damper, with a coolant heater and an electromagnetic valve of the idle system.
