What It Helps Address

• Evaporative emissions leaks related to a saturated or damaged vapor canister
• Fuel vapor odor caused by poor vapor storage or routing
• Check-engine concerns tied to EVAP system faults
• Improper venting in the fuel vapor control circuit
• Reduced evaporative system performance on Ram 3500 trucks

Installation Notes and Tips

Verify the vehicle’s EVAP layout before installation, especially on 2012-2014 Ram 3500 trucks with a vapor canister vent valve and Leak Detection Pump. Match the connector style, port count, and hose routing to the original unit before removal. Confirm all vapor lines are seated securely and inspect related EVAP components for damage or contamination during service.

Quality Assurance

Standard Ignition manufactures this vapor canister to OE specifications for direct replacement use. The integrated check valve and application-specific pressure calibration are designed around the vehicle’s evaporative emissions requirements.
