2901002100 Steam Tank Purge Control Valve Overview A replacement purge control valve designed to manage the controlled release of stored vapors from the steam/fuel vapor tank back into the engine intake for combustion. This part is identified by OEM part number 2901002100 and is intended as a directfit replacement where that part number is specified. Key benefits — why you need it Restores proper vapor purge operation: replaces worn or leaking valves that cause rough idle, check engine lights related to EVAP/steam purge faults, or increased evaporative emissions. Improves fuel vapor control: returns trapped vapors to combustion instead of allowing uncontrolled venting, helping emission systems function as designed. Directfit replacement: designed to match the original part number 2901002100 so installation is straightforward when used in compatible systems. What this part solves Prevents EVAP/steam tank purge malfunctions that can trigger diagnostic trouble codes or cause drivability issues. Stops leaks and intermittent flow problems that reduce system efficiency or cause fuel odor. Provides reliable control of purge timing and flow to help maintain emission compliance and engine performance. Key attributes Functionality: Controls the purge flow from the steam/vapor tank to the intake manifold during purge cycles; designed to operate as the system's vapor control valve. Compatibility: Intended as a direct replacement for components specified by part number 2901002100. Verify vehicle or equipment fitment against this part number before . Size and fit: Compact, OEMfit design to match original mounting points and connections for straightforward replacement (check existing valve for physical match). Material and construction: Built to OEM specification for durability and corrosion resistance to withstand underhood operating conditions. Performance: Engineered to provide consistent, repeatable purge control for reliable system operation and to reduce the likelihood of evaporative emission faults. Typical applications / use cases Routine maintenance: a failing or aged purge control valve during EVAP system service to restore proper vapor purge function and prevent diagnostic codes. Fault diagnosis : Swap in this valve when diagnosing a persistent EVAP/steam purge error code, vacuum leak, or unexplained fuel odor. Fleet and heavyduty service: Use as a service replacement part for vehicles or equipment that specify part number 2901002100 to maintain emission controls and operational reliability. Installation and maintenance notes Confirm fitment: Match the OEM part number 2901002100 and visually compare mounting points, electrical connectors, and hose fittings prior to installation. Basic installation: Typically replaces the original valve using the same mounting hardware, vacuum/purge lines, and electrical connector; follow vehicle or equipment service manual for torque and procedure. Inspection: When installing, inspect associated hoses, clamps, and connectors for damage or wear and as needed to prevent future leaks. Testing: After installation, verify system operation and clear any diagnostic trouble codes; perform a smoke or pressure test if applicable to confirm leak operation.
