Vapor (or vapour) recovery is the process of collecting the vapors of gasoline and other fuels, so that they do not escape into the atmosphere. This is often done (and sometimes required by law) at filling stations, to reduce noxious and potentially explosive fumes and pollution.

The negative pressure created by a vacuum pump typically located in the fuel dispenser, combined with the pressure in the car's fuel tank caused by the inflow, is usually used to pull in the vapors. They are drawn in through holes in the side of the nozzle and travel along a return path through another hose.

In Australia, vapor recovery has become mandatory in major urban areas. There are two categories - VR1 and VR2. VR1 must be installed at fuel stations that pump less than 500,000 litres annually, VR2 must be installed for larger amounts, or as designated by various EPA bodies.
