Detailed Product Overview

This ported vacuum switch is used in GM emission-control setups where vacuum signal control is required for proper system timing and operation. Standard Ignition PVS67 is engineered for vehicles such as the Chevrolet C10, GMC K1500, and Pontiac Firebird, with fitment spanning 1979-1985 model years across multiple GM car, truck, and van platforms. The part number PVS67 is a practical replacement choice when the original switch has aged, cracked, or no longer routes vacuum correctly.

This part cross-references 2-29032 and 7P1070 for the same application.

What This Part Helps Correct

Incorrect vacuum routing in emission-control circuits
Delayed or inconsistent vacuum switching
Hard-to-diagnose drivability issues tied to worn vacuum controls
Leaks caused by deteriorated plastic housings or fittings
Fitment problems from mismatched thread or connector style

Installation Notes and Tips

Verify the original switch style, port count, and thread size before installation. Match the vehicle’s emissions configuration, including Canada-emissions and dark blue 2-port applications where listed. Inspect vacuum hoses for brittleness, cracks, or loose connections before installing the new switch, and confirm all hose routing matches the factory layout.

Quality Assurance

Standard Ignition manufactures emission components with quality control maintained throughout production, from component selection to finished part inspection. The PVS67 is built to OEM specification for precision fit and dependable performance.
