Detailed Product Overview

This Dorman vapor canister is engineered to mirror the original EVAP canister used on select Jeep Commander and Jeep Grand Cherokee vehicles. The charcoal media stores fuel vapors from the fuel system until the engine management system purges them, helping maintain emissions control performance. Dorman 911-342 is a practical OE-style replacement when the original canister is cracked, saturated, or no longer functioning correctly.

Key construction details include a plastic housing, plastic connector material, a rectangular female connector, two male blade terminals, and two ports sized to match the original layout. The canister measures 317.5 in length and uses charcoal filter elements to support evaporative system operation. This part cross-references Standard Ignition CP3151 for the same application.
