Purpose and function in the fuel system

The presented tank belongs to the Fuel tanks and filler pipes category and is dedicated to BMW M3 E46 cars with a petrol engine. Its task is to safely store fuel, ensure stable supply to the engine unit, and work in conjunction with factory equipment – the fuel pump, level sensor, and supply lines.

• correct routing of fuel and vent lines,
• stable mounting at factory body points,
• compatibility with the original fuel filler and filler pipe,
• maintenance of the correct fuel system operating capacity.

As a result, replacing a damaged or corroded tank with this component allows you to restore proper fuel system operation without interfering with the body structure.

Technical and material characteristics
