Help your fuel vapor system check itself for leaks with the Dorman evaporative emissions system leak detection pump, part number 310-233, an OE Solutions part that Dorman also lists as an Evaporative System Integrity Module. It fits many vehicles, among them the 2007-2008 Dodge Ram 1500, 2020-2021 Dodge Charger and 2014-2021 Jeep Cherokee. See the Buyer's Guide tab for the full list and engine details.
The EVAP system captures fuel vapor from the tank and sends it to the engine instead of venting it to the atmosphere. This leak detection pump / integrity module is used to check that sealed system for leaks. If a clogged or failed unit is behind an evaporative-system fault on your vehicle, this part replaces it.
- Direct replacement: designed to fit and work like the original pump on the listed applications.
- Replaces failed units: intended for an original unit that has clogged or stopped working as a result of damage within the emissions control system.
- Durable construction: made from quality materials for dependable performance and durability.
- Backed by experience: supported by Dorman's team of product experts in the United States and more than a century of automotive experience.
Signs this part may need replacing include an illuminated check engine light with evaporative-system codes or a failed emissions inspection. Hoses, seals, the gas cap and other EVAP components can cause the same signs, so diagnose the cause before replacing.
