What Is a Fuel Rail?

Supplying high-pressure fuel to the engine combustion chamber

A fuel rail, one of the critical components of the fuel injector, is responsible for stably supplying fuel, such as gasoline, to the injector. Used in advanced direct-injection gasoline engines, a fuel rail helps achieve high levels of fuel efficiency and environmental performance.

Features of our fuel rail

  • Made of stainless steel to achieve excellent environmental, fuel, and corrosion resistances.
  • Structured based on soldering to achieve higher design flexibility and lower production costs.
  • Optimized in shape to achieve both of lightness and resistance to high pressures
