FIELD: engines and pumps.
SUBSTANCE: invention can be used in fuel fed systems of internal combustion engines. The steel fuel fed line for petrol supply from the high pressure pump to a direct injection manifold in the system of the petrol engine with direct fuel injection is offered. Along the whole internal circumferential surface of the fuel fed line the layer of nickel coating with the thickness from 1 to 15 micrometers, and above the layer of anticorrosive film consisting of zinc coating layer or a layer of zinc-based alloying coating with the thickness from 0.1 to 8 micrometers and with the length to the position from D to 6D mm (where D - pipeline diameter) from the end of the fuel fed line to the inside is provided.
EFFECT: increase of resilience to corrosive fuels and ensuring reliability without damage of an internal combustion engine.
