Jeep Emission Controls

This evaporative emissions system leak detection pump filter is designed to match the fit and function of the original filter on specified applications, and is engineered for reliable performance and durability.

The vehicle fuse block is generally a cluster or array of fuses and/or relays to control various circuits in the vehicle. Normally, it is separate from the primary fuse box or fuse and relay center. Dorman fuse blocks are built with safety and longevity in mind to help ensure the integrity of the electrical system in today’s automobiles.

Carquest Evaporative Emissions System Leak Detection Pump Filter, VDC1201.

The Evaporative Emission System is designed to control fuel vapors in the vehicle fuel storage system to prevent any release of fuel vapors into the atmosphere. In a normally operating system, released vapors from the fuel storage tank will be directed into an on-board charcoal canister via a piping system and control valves. Under the most ideal engine operating condition, the vapors will be pulled into the engine to be burned during the normal combustion process. The leak detection pump uses naturally changing vacuum due to temperature change as well as the pressure change during the normal evaporative purge process to transition a normally open vacuum switch indicating normal operation or system failure.
