Fuel rails are typically rectangular in shape to provide a streamlined, compact design that allows for efficient fuel distribution to multiple fuel injectors. This shape helps maintain a consistent fuel pressure across the rail, ensuring even delivery to each injector. Additionally, the rectangular profile facilitates easier integration into the engine compartment, optimizing space and minimizing weight. The design also allows for effective cooling of the fuel as it circulates.
