Q: How do I replace Vapor Canister,Canister Purge Valves and Fuel Pressure Sensor in a Buick Enclave,Chevrolet Traverse and GMC Acadia?
A: To remove the fuel tank pressure sensor, take out the fuel tank, disconnect the connector, and remove the sensor from the fuel pump module. To remove the EVAP canister, raise the vehicle, remove the fuel tank, disconnect the connector and hoses from the canister on top of the tank, and remove the retainer and the canister. Installation is the reverse of removal.
