The EVAP vacuum leak pump assembly contains the fuel tank pressure (FTP) sensor, the canister vent solenoid, and an electric motor driven vacuum pump. The vacuum pump provides pressure for leak testing when the engine has been OFF for approximately five hours. The pump assembly also has several internal filters and a 0.5 mm (0.020 inch) reference orifice. The reference orifice provides controlled movement of the pressure within the system, enabling the FTP sensor to accurately monitor system performance. The complete pump assembly is mounted on the EVAP canister, eliminating the need for additional hoses or lines for connections.
