The Fuel Main Hose Assembly used in the main fuel lines is responsible for delivering fuel to the fuel manifold in the engine. It is used to ensure a reliable and uninterrupted flow of fuel while maintaining the necessary pressure and preventing any leaks. The tube assembly includes a bulk hose, bulk tube, sleeve fittings, straight coupling, and swivel nuts that are installed in a specific configuration to ensure proper routing and connection to the fuel manifold and the engine.Attributes:• Manufactured to precise specifications and built for durability and reliability• Withstands a high fuel pressure of about 3500 kPa without deforming or breaking• Provided with a 4.57mm ID tube, 37° flared JIC 7/16" swivel nut, and 11/16" straight coupling for a tight and secure connectionApplications:The Fuel Main Hose Assembly is used to transfer high-pressure fuel to the fuel manifold in the engine and supply precise and consistent fuel to the engine, preventing loss of pressure and fuel leakages.
