Where is the 2008 chevy silverado purge valve solenoid located?

The evap canister, also known as the purge valve, on the 2008 Chevy Silverado is located to the left of the brake booster and master cylinder on the driver side firewall. The EVAP canister is filled with activated charcoal and is designed to catch the emissions that are put off by Your car and trap them. This makes the car better for the environment, and it makes it healthier for You to be inside of it. If the canister has failed then You will notice a fuel smell in the cab of the car, though it may also smell like rotten eggs. This is unhealthy to breathe in the long run, and it will make the car fail an emissions test, which You can be ticketed for. If You notice such a smell or get a trouble code, You need to take the car to the shop.
