Good To Know

Q: What does a vapor canister actually do? A: It traps fuel vapor from the tank and releases it for the engine to burn instead of letting it escape. A failed canister can cause fuel smell, hard starting after fueling, or evap codes.

Q: Is this an original Chevrolet part? A: No, this is an aftermarket replacement component that cross-references OEM number 911478. Always confirm fitment against your vehicle's serial number and engine before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
