F1: FIA issues new fuel-flow clampdown

The FIA has sent Formula 1 teams a new technical directive clamping down on fuel pressure and fuel-flow rates.

AUTOSPORT revealed at the Australian Grand Prix the FIA had issued a directive allowing it to measure fuel pressure throughout each car's fuel system. The location of the previous fuel-flow sensor made it possible in theory to accumulate fuel between the sensor and the fuel injectors.

That fuel could then be pumped into the engine at a greater pressure and/or fuel-flow rate, which is limited to 100kg/h, to boost engine power beyond what is permitted by the regulations.

On Saturday, the FIA sent teams a further directive to teams clarifying what they are allowed to do. It specified that fuel pressure in the high and low pressure systems must "remain constant above a flow rate of 90kg/hr," meaning it must stay in the 90-100kg/hr rate at all times.

The governing body added that it does not "consider it necessary to define here what we consider constant" but will instead speak to the relevant teams should an issue arise.

The FIA plans to carry out physical inspections of all fuel systems to ensure they comply with the regulations.
