The Carter SX-4896 In-Line Electric Fuel Pump features a robust design with a high-performance, 12-volt electric motor that delivers an impressive flow rate of up to 25 GPM (gallons per minute). This ensures that your Mazda RX-3 receives the optimal amount of fuel needed for efficient engine performance and smooth operation.

This fuel pump is designed as an in-tank unit, meaning it is installed directly into the fuel tank.

These materials ensure the pump's longevity, even in harsh fuel conditions. The pump also comes with a built-in, heavy-duty strainer that helps filter out debris, ensuring the fuel delivered to your engine remains free from contaminants.

This fuel pump is easy to install and comes with a pre-wired wiring harness that simplifies the process. The harness includes a fuel level sender, making it a direct replacement for your original fuel pump. Additionally, the pump is compatible with both EFI (Electronic Fuel Injection) and carbureted engines, giving you the flexibility to choose your preferred fuel delivery system.

In conclusion, the Carter SX-4896 In-Line Electric Fuel Pump is a high-performing, reliable, and durable component that ensures your 1972-1974 Mazda RX-3 with a 1.1L R2 engine receives the optimal fuel supply for efficient engine performance and smooth operation.
