Alcohol Solenoid .312

The Alcohol Solenoid .312 from Wilson Manifolds is a precision fuel control component engineered for high-performance and racing applications where methanol or ethanol-based fuel systems demand reliable solenoid actuation. This component serves as the critical interface between your engine management system and alcohol fuel delivery, ensuring precise metering and rapid response during boost events. Whether you're running a dedicated methanol injection kit, a full alcohol fuel system on a turbocharged or supercharged engine, or upgrading an existing carbureted race platform, this solenoid delivers the consistent performance that serious competitors and enthusiasts depend on for repeatability and power.

The .312 designation refers to the solenoid's orifice size—a critical specification that determines fuel flow rate and injection timing precision under load. Wilson Manifolds engineered this solenoid to handle the corrosive and demanding nature of alcohol fuels, which require different material compatibility and sealing specifications than conventional gasoline systems. The compact 5.9 x 1.85 x 6.2 inch form factor and 1.04 lb weight allow flexible mounting options on manifolds, fuel rails, or injection blocks without adding significant mass or complexity to your fuel system plumbing. This solenoid's rapid switching capability ensures that alcohol fuel pulse widths remain accurate across the full RPM range, maintaining consistent combustion timing and preventing lean-out conditions during transient throttle events.

Professionals building alcohol-injected naturally aspirated engines, turbocharged street/strip machines, and dedicated methanol race cars will find this solenoid essential for system reliability and tuning precision. Installation typically involves mounting to your fuel manifold assembly or standalone injection block, with electrical connections routed to your engine management module or dedicated methanol controller. Confirm your fuel system's pressure rating and flow requirements against the .312 orifice specification to ensure optimal injector duty cycle and response. This component pairs seamlessly with Wilson Manifolds fuel rails and injection systems, making it the ideal choice for builders committed to professional-grade alcohol fuel control.
