Connecting The Manometer
Expose the canister purge (CP) valve.
Disconnect the hose (1) between the EVAP canister and the EVAP canister purge valve.
Connect manometer see 9995646 to the hose (1) and the pressure regulator see 9995544 to the manometer.
The cock should face the pressure regulator.
Connect compressed air to the pressure regulator
Set the pressure to a maximum of 7 kPa (read off from manometer 999 5646).
Pressurize the fuel tank system by turning the cock at right angles to the hoses.
Allow pressure to build up in the tank system.
Check that the system does not leak.
Stop the pressurization by turning the cock towards the hose (1) as illustrated by "A " in, see Fig 1.
A certain amount of leakage may occur from the leak diagnostic unit. The pressure may therefore drop when the pressurization is stopped. This is normal. The leakage is caused because the pressurization is not carried out using the leak diagnostic unit.
Never leave the car unattended with the tank system pressurized
