Fuel System Hydraulic Layout as described by schematic in article 6.6

In Simple Terms

This regulation defines the low-pressure part of an F1 car's fuel system - basically everything from where fuel enters the tank up to the point it goes into the high-pressure pump. It covers the pipes, filters, valves, and pumps that safely deliver fuel at lower pressures before it gets compressed for the engine.

• Covers the low-pressure section of fuel delivery from lift pump inlet through to the high-pressure pump entrance
• Specifies approved components including filters, relief valves, non-return valves, breakaway valves, and rigid piping
• Includes safety devices like pressure relief valves and breakaway valves to prevent fuel leaks during crashes
• Allows optional components like dampers and inlet filters to optimize fuel system performance
