Detailed Description

Dorman 911-335 is an evaporative system vapor canister engineered to match the original equipment unit on specific vehicle years, makes, and models. The canister uses a charcoal filter element to capture fuel vapors and route them through the EVAP system, helping maintain proper emissions control operation. Its plastic housing, rectangle connector shape, and OE-style port arrangement support a factory-like replacement on the Jeep Compass, Jeep Patriot, and Dodge Caliber.

This part cross-references Standard Ignition CP3316 for the same application.

Installation Notes and Tips

Verify vehicle emissions configuration before ordering, especially for 2014-2017 Jeep Compass and 2014-2017 Jeep Patriot models with Federal Emissions. Confirm connector style, port count, and port diameters against the original part before installation. Inspect EVAP hoses, seals, and related lines for wear or cracking during replacement so the new canister can operate correctly.
