Useful Information

Description and Purpose:

The heavy-duty exhaust systems in your Chevrolet Silverado or GMC Sierra rely on this Genuine GM Diesel Emissions Fluid (DEF) Supply Pump Module to function, which is new and cataloged under Part number: 19300179. This unit serves as the pressurized heart of the SCR system, drawing fluid from the tank to treat the exhaust of 2.0L and 6.6L diesel engines found in the Express, Savana, and Silverado series. Interchange part numbers: 20927437, 20953677, 20972650, 20981185, 22785207, 22905127

Why Replacement is Important:

A failed pump triggers restrictive speed limiters and persistent "service exhaust" warnings. Replacing the module is necessary to restore pressurized delivery, allowing the vehicle to exit "limp mode" and clearing the fault codes that prevent normal operation.

Impact on Vehicle Performance:

Installing this unit ensures your truck maintains its full torque and towing capacity while remaining emissions-legal. It prevents the engine from de-rating, keeping your fleet dependable for high-demand hauling and industrial work.

Manufacturer Information:

General Motors® delivers trusted automotive components designed for accurate integration, consistent performance, and lasting vehicle reliability.
