What does the leak detection pump do and why replace it?

The leak detection pump is a component of the EVAP system that pressurizes and monitors the fuel vapor containment circuit for leaks. A faulty pump can trigger diagnostic trouble codes and allow vapors to escape, so replacing a failing unit restores proper EVAP diagnostics and helps maintain emissions controls.

• Performs pressurized checks of the fuel vapor lines
• Sends signals to the vehicle’s emissions control module
• Prevents uncontrolled fuel vapor release when working correctly
• Often replaced when EVAP-related DTCs or persistent leaks appear

What’s included and any installation notes?

The package contains one fuel vapor leak detection pump and is supplied as a direct replacement part. Installation generally requires basic mechanical skill and common hand tools. Follow safety procedures for working near fuel components and verify all connections for leaks after installation.

• Included: 1 × fuel vapor leak detection pump (310-219)
• Tools: screwdrivers, ratchet set, possibly trim removal tools
• Post-install: clear codes and perform EVAP system test per service manual
• Note: confirm part visually against the removed unit before mounting

Who is this for: This stymart 310-219 replacement pump is intended for mechanics, fleet service techs and informed DIY vehicle owners working on compatible Chrysler, Dodge, Fiat, Jeep, Ram or Alfa Romeo models who need an OE-number-matching EVAP leak detection pump.
