Ported Vacuum Switch for GM Emissions Control

Standard Ignition PVS102 is a ported vacuum switch built for precise emissions-system control on select Chevrolet and GMC trucks, vans, and utility models. It uses a brass and high-temperature plastic housing built to OEM specification for accurate fit and consistent operation.

Compatible With 1983-1990 Chevrolet and GMC applications, including Chevrolet C10, K10, C1500, K1500, P30, and GMC C1500, K1500, P3500 models.

Key Features

Ported vacuum switch for emissions and vacuum routing control
Brass and high-temperature plastic construction
OEM-spec fit and performance
Special thermal elements for improved operation
2 hose connectors with 3/16" x 3/16" hose size
3/8"-18 NPT thread size

Detailed Description

The Standard Ignition PVS102 is engineered for GM vacuum control systems that rely on a ported vacuum switch to manage emissions-related routing. Its construction combines brass with a high-temperature plastic housing, and the thermal elements are designed to improve switching performance under operating heat. This part cross-references 2-29215 for the same application.

Use this ported vacuum switch when servicing Chevrolet and GMC models such as C10, K20, K3500, G30, P30, and related 1983-1990 truck and van platforms. The PVS102 part number is also a useful reference when sourcing an OE-style replacement for older GM emissions hardware.

What It Helps Address

Vacuum routing problems in emissions control circuits
Incorrect EGR vacuum switching behavior
Heat-related failure of aging plastic vacuum components
Hard-to-match replacement needs for older GM truck and van applications
Restoration of factory-style vacuum control on select Chevrolet and GMC models

Installation Notes and Tips

Verify hose size, thread size, and port count before installation. This switch uses two hose connections with 3/16" x 3/16" hose sizing and a 3/8"-18 NPT thread. Confirm the vehicle’s emissions configuration and compare the original part before replacement, especially on 1984-1985 California emissions applications and gray 2-port variants.

For fitment, this part is listed for 1990 Chevrolet C1500, C2500, C3500, G30, K1500, K2500, K3500, P30, R2500 Suburban, R3500, V2500 Suburban, and V3500; 1990 GMC C3500, G3500, K3500, P3500, R2500 Suburban, R3500, and V3500; and earlier 1983-1989 Chevrolet and GMC truck, van, and Suburban applications shown in the fitment data.
