One of the most important components of the powertrain fuel system is the fuel hose. The stability of the diesel engine depends on its integrity. The fuel hose is used to supply and distribute fuel between the injectors. In the rail, the fuel is under pressure. In the era of carburetors, when an element such as a tube was not provided, the situation was different. Fuel was not supplied under pressure. With the development of technology, as well as the improvement of gasoline power units, the fuel hose migrated from diesel cars. It has become an irreplaceable component of the structure.

The usage of the fuel hose

The main job of the SWAG brand Fuel Hose is to deliver and distribute fuel directly between the engine injectors. The fuel is in each case under pressure. To ensure a long service life, the fuel hoses are made of corrosion-resistant steel. In addition, the design provides for a special connection for the pressure gauge. It allows pressure control. A separate valve can also be located on the fuel hose for draining fuel, both during maintenance and repair.
