The Delphi SX-5719 in-tank electric fuel pump is a superior replacement option for the original fuel pump in 1989 Chevrolet R2500 vehicles equipped with the 5.7L and 7.4L V8 engines and automatic transmissions. This fuel pump is specifically designed to fit and function seamlessly in these applications, ensuring optimal fuel delivery to the engine.

This Delphi SX-5719 fuel pump is an electric in-tank design, meaning it is located within the fuel tank and relies on an external electric power source to operate.

This system automatically activates when the fuel temperature reaches a certain threshold, allowing cooler fuel to flow through the pump, maintaining efficient operation.

This Delphi fuel pump comes with a factory-installed O-ring gasket, ensuring a secure seal between the pump and the fuel tank. It also includes a new fuel filter, which helps prevent debris and contaminants from entering the fuel system and damaging the fuel pump or engine.

Installation of the Delphi SX-5719 fuel pump is a relatively straightforward process for experienced DIYers or professional mechanics. The pump comes with clear and concise installation instructions, as well as all necessary hardware and connectors for a hassle-free installation.
