Dorman Evaporative Emissions Leak Detection Pump 310-218 — Direct-Fit EVAP Replacement, Corrosion-Resistant

The Dorman 310-218 is a direct-fit evaporative emissions leak detection pump engineered to replace the original unit and restore proper EVAP system diagnostics.

This replacement pump matches the fit and function of factory parts for many Chrysler, Dodge, Jeep and Ram vehicles.

How does this pump help my vehicle’s evaporative emissions system?

The pump pressurizes and tests the EVAP plumbing to detect small leaks in the fuel vapor containment system. A working leak detection pump enables the vehicle’s onboard diagnostics to run evaporative leak tests, reducing false fault codes and improving readiness checks.

• Restores EVAP test pressure for the vehicle’s diagnostic routine
• Helps eliminate intermittent or stored EVAP trouble codes
• Works as a direct replacement for original pump fit and function

What should I expect when installing the replacement pump?
