310-219 Fuel Evaporative Emissions Leak Detection Pump

This replacement leak detection pump is designed to match the original equipment specification OE 310-219 and restore EVAP system function on a wide range of vehicles from 2007 through 2019. It performs pressurized checks of the fuel vapor lines to detect leaks and reseals the system so the onboard diagnostics can run correctly. The unit ships as a single pump and should be verified against the vehicle’s part number and photos before installation to ensure proper fitment.

Which vehicles does this pump fit?

This pump covers many popular compact cars, SUVs, trucks, and vans across FCA platforms. Compatibility includes specific years for Alfa Romeo, Chrysler, Dodge, Fiat, Jeep and Ram ProMaster variants. Always compare the part visually and by OE number to be sure it’s the correct component for your vehicle.

• Alfa Romeo 4C: 2015–2019
• Chrysler Aspen: 2007–2009
• Dodge Durango: 2007–2008, 2011–2019

• Dodge/Ram 1500: select years 2009–2019
• Fiat 500 & 500L and multiple Ram ProMaster models (2012–2019 ranges)

How does this part restore EVAP functionality?

The pump pressurizes and monitors the evaporative emissions circuit so the engine control module can perform leak diagnostic tests. A functioning unit prevents uncontrolled vapor escape and enables the vehicle to complete onboard EVAP readiness checks. Faulty pumps often trigger check-engine lights and failed emissions readiness.

• Performs pressurized leak tests on the EVAP circuit
• Interfaces with vehicle wiring and control logic like OEM units
• Helps clear EVAP-related diagnostic trouble codes when installed correctly

What should I check before buying and installing?

Confirm the OE number (310-219) and visually match the pump to the removed part or the vehicle illustration. Inspect connector type, mounting points and hose fittings to avoid installation issues. If you’re unsure, have the vehicle’s VIN and the original part number handy when ordering.

• Compare OE number 310-219 and photos before purchase
• Verify electrical connector and vacuum/hose port locations
• Keep vehicle VIN or original part for fit confirmation

Can I replace this myself or should a technician do it?

Replacement is achievable for DIYers with basic mechanical skills, proper tools, and safety precautions, but access to the EVAP components varies by model. If the pump is in a cramped location or wiring must be diagnosed, a professional install is recommended to avoid damage and ensure diagnostics run afterward. After replacement, a scan tool may be needed to clear codes and run EVAP tests.

• DIY: moderate difficulty, requires basic tools and hose/connector handling
• Pro install: recommended if wiring or diagnostic troubleshooting is necessary
• Post-install: scan tool useful to clear codes and verify EVAP readiness
