What is the purpose of the roll-over valves and how can they be removed and installed on Ford Focus?

The roll-over valves are located in rubber grommets in the top of the fuel tank, with hoses leading rearwards to the carbon canister. Their purpose is to prevent fuel loss if the vehicle becomes inverted in a crash. To remove the roll-over valve, start by removing the fuel tank and releasing the vent hose from the clip on the top of the tank. Carefully pry the roll-over valve from the rubber grommet and remove it along with the hose. Make sure to check the condition of the rubber grommet and replace it if necessary. For installation, simply reverse the removal steps and apply a light smear of clean engine oil to the rubber grommet to ease the installation process.

Ford Focus Fuel Tank Vent Valve

A Fuel Tank Vent Valve in Ford Focus vehicles serves as an essential component that belongs to the evaporative emission control (EVAP) system to stop gasoline vapors from leaking into the environment. The vapor distribution sequence of the Fuel Tank Vent Valve allows excess fuel pressure management while redirecting vapors to the charcoal canister to maintain emissions control. The valve allows vapors to pass through under two conditions: both the powertrain control module (PCM) recognizes a leak in the EVAP system and the vent valve receives a control signal from the PCM. Multiple Fuel Tank Vent Valve designs have run in Ford Focus vehicles from different production years but no particular models are listed in the available information. Control of vapor emission is the fundamental objective of the Fuel Tank Vent Valve which continues this role as a requirement to meet environmental requirements. The price of new Ford Focus Fuel Tank Vent Valve replacement varies at reasonable prices based on the specific car model type.
