The Carter SX-4523 in-tank electric fuel pump is specifically designed for use in 1999-2004 Nissan Frontier vehicles equipped with a 3.3L V6 engine and air cooling system. This fuel pump is an essential component of the vehicle's fuel delivery system, responsible for supplying fuel from the tank to the engine.

The harness includes all necessary connectors and terminals, allowing you to easily connect the pump to the vehicle's electrical system. The pump is also compatible with the factory fuel level sender, allowing for easy integration with the vehicle's existing fuel system.

The Carter SX-4523 fuel pump is designed to meet or exceed OEM specifications, ensuring reliable and consistent performance. This pump is also backed by a 12-month limited warranty, giving you peace of mind and protecting your investment.

In summary, the Carter SX-4523 in-tank electric fuel pump is a high-quality, durable, and efficient replacement for the original fuel pump in 1999-2004 Nissan Frontier 3.3L V6 engines. Its quiet operation, improved fuel economy, and easy installation make it an excellent choice for those seeking to enhance their vehicle's fuel system performance.
