Top 5 Applications for Automotive oil hose

Fuel Transportation

The primary function of automotive fuel hoses is to deliver fuel from the fuel tank to the engine. This ensures a steady supply of fuel to power the vehicle.

Fuel Injection Systems

In modern vehicles equipped with fuel injection systems, fuel hoses are vital for delivering pressurized fuel to the injectors. These hoses must withstand high pressures and temperatures to ensure proper engine performance.

Emission Control Systems

Some vehicles use fuel hoses in emission control systems, such as evaporative emission control systems. These hoses help transport fuel vapors from the fuel tank to the emissions tank for storage or recirculation.

Cooling Systems

In some cases, automotive fuel hoses are used in the cooling system to transfer coolant between the engine and the radiator. These hoses are designed to withstand the high temperatures of the engine compartment.

Brake system

Certain vehicles, especially heavy-duty trucks and equipment, use hydraulic systems for various functions such as power steering, braking or suspension. Fuel hoses can be used in these systems to transport hydraulic fluid.
