A Fuel Tube Assembly is placed in the cylinder block for the fuel unit that connects the fuel injector lines with the fuel source, such as the fuel filter and pump. The tube assembly includes a bulk tube, O-Ring Face Seal (ORFS) sleeves, and swivel nuts that are connected in a specific configuration to ensure proper routing and connection to the engine and fuel filter. Its primary function is to transport pressurized fuel from the fuel filter to the fuel injector lines, which then spray the fuel into the engine's combustion chamber for efficient combustion.Attributes:• Provided with 37° single flared sleeve, ORFS sleeve, and nuts for a tight and secure connection• Withstands a 240 kPa fuel pressure without deforming or breakingApplications:A Fuel Tube Assembly is used to conduct high-pressure fuel from one point to another within the fuel filter lines and supply precise and consistent fuel to the engine, preventing loss of pressure and fuel leakages.
