The Dorman 310-219 is a direct-fit evaporative emissions system leak detection pump engineered to restore EVAP system function and match the original equipment's fit and performance on specified vehicles.

This replacement leak detection pump from Dorman is built to the same mounting and connection style as the original unit so it installs without major modifications.
