Fuel pressure limit

Chapter: C5

In Simple Terms

F1 teams cannot pump fuel into their engine's fuel injectors at a pressure higher than 350 bar (a unit of pressure). This limit ensures the fuel system operates safely and prevents teams from gaining an unfair advantage through excessive fuel pressure.

  • Maximum fuel pressure to injectors is capped at 350 barG (bar gauge)
  • This regulation applies specifically to the fuel supplied directly to the fuel injectors
  • The limit ensures fair competition and prevents damage to engine components
  • Teams must monitor and control their fuel system pressure during all sessions
Official FIA Text

The pressure of the fuel supplied to the Fuel Injectors may not exceed 350barG.
