Ported Vacuum Switch for Emissions Control

Standard Ignition PVS71 is a ported vacuum switch built for emission-system control on a wide range of classic Chevrolet, GMC, Jeep, Buick, and Pontiac applications. It uses a brass and high-temperature plastic housing built to OEM specification for precise fit and consistent operation.

With two hose connectors, 3/16" x 3/16" hose sizing, and a 3/8"-18 NPT thread, the PVS71 is specified for vehicles that rely on accurate vacuum routing for EGR and related thermal switching functions.

What This Part Helps Address

Incorrect vacuum routing in temperature-controlled emission systems
EGR operation issues caused by a worn or failing vacuum switch
Vacuum leaks at the switch body or hose connections
Delayed or inconsistent thermal vacuum switching
Driveability concerns tied to emission-control vacuum management

Installation Notes and Fitment Tips

Verify the vehicle’s emissions calibration, hose size, and thread specification before installation. This part is listed for white 2-port applications across many fitments, including 1980 Chevrolet Caprice, 1980 Chevrolet Monte Carlo, 1980 Chevrolet Camaro, 1980 Buick Century, and 1980 Pontiac Firebird. Additional fitment includes 1981-1985 Jeep CJ7, 1981-1985 Jeep Wagoneer, and 1978-1979 Chevrolet C10 Suburban with California emissions notes where specified.

Confirm the original switch style and port count against the removed component to ensure the correct replacement for your Chevrolet or GMC truck, Jeep emissions system, or classic GM passenger car.
