Specifications

1979 Volvo 264 265

Evaporative control system

Vehicles intended for the North American market are equipped with a gas vapor evaporative control

system, which prevents gas fumes from being released into the atmosphere.

The system is comprised of an expansion area in the fuel tank, a pressure relief valve and a charcoal

filter in the engine compartment.

The components are interconnected by hoses which channel fuel fumes from the gas tank to the charcoal

filter where they are stored until the engine is started and then drawn into the engine fuel induction

system.
