Bosch Fuel Vapor Leak Detection Pump

The Bosch Fuel Vapor Leak Detection Pump, also called an EVAP leak detection pump or evaporative emissions leak detection pump, is part of the vehicle's evaporative emission control system. It tests the fuel vapor system for leaks so that fuel vapors stay out of the atmosphere. It also helps the engine control module run its on-board diagnostic EVAP monitor.

Key Features:

• Pressurizes the fuel vapor system during the diagnostic test so the engine control module can detect small leaks
• Helps prevent evaporative emission faults, such as a check engine light from a leak code
• Built to meet original equipment requirements for fit, function and durability
• Backed by Bosch's engineering experience and quality standards as an OE supplier
• Replaces the factory leak detection pump (LDP) or smoke/vacuum pump for reliable EVAP system monitoring

Replacing a worn or failed leak detection pump helps restore proper evaporative system monitoring and emissions compliance. It also helps keep fuel vapors contained. Each part number in this product line is made to the Bosch quality standard.
