Genuine BMW – Mini Fuel Vapor Detection Pump

The Genuine BMW/MINI Fuel Vapor Detection Pump, also called a leak diagnostic pump, leak detection pump, DMTL pump or EVAP leak detection pump, is an original-equipment component of the fuel evaporative emissions system. It pressurizes the fuel tank and evaporative system so the engine control unit can check for vapor leaks to the atmosphere.

Key Features:

• Genuine BMW/MINI quality built to original-equipment specifications for a precise fit and dependable operation
• Tests the fuel containment and evaporative emissions system for vapor leaks
• Replaces a failed pump that can't pressurize the system, which may turn on the check engine light with an evaporative emissions fault code
• Helps the vehicle pass emissions inspections in areas that require them

Replacing a worn or failed fuel vapor detection pump with a genuine part restores normal evaporative system self-diagnosis and helps keep the fuel system working as designed.
