Bosch Fuel Vapor Detection Pump

The Bosch Fuel Vapor Detection Pump, also called an EVAP leak detection pump, leak diagnosis pump, or evaporative emissions leak detection module, is a key part of a vehicle's evaporative emission control system. It checks the fuel vapor system for leaks so the vehicle can meet emissions requirements and keep fuel vapors out of the atmosphere.

Key Features:

• Leak monitoring: Pressurizes the EVAP system and checks it for leaks as part of the vehicle's self-diagnostic routine.
• Emissions compliance: Helps the EVAP system stay sealed and working as designed, which can prevent EVAP-related check engine lights and fault codes.
• OE technology: Bosch is an original equipment supplier. These pumps are built to match original equipment fit, form, and function.
• New product: Designed for dependable, long-lasting operation.

Bosch has a long record of automotive engineering and emissions technology. It introduced the automotive oxygen sensor in 1976. Choose the child item that matches your application from the options listed on this page.
