The evap canister, also known as the purge valve, on the 2004 Dodge Ram 1500 4 7 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.

Wow...the evap canister is not also known as a purge valve. The purge valve comes after the canister with a solenoid that opens it to send vapors to the engine to be combusted. The canister has charcoal filters in it...totally separate from the purge valve. Please know what you are talking about before answering a question.
