F1: FIA issues new fuel pressure directive

The FIA has issued a technical directive to allow it to measure fuel pressure throughout each car's fuel system.

The directive, issued on Sunday, calls for teams to measure the pressure at multiple points in the fuel system. This is on top of the FIA fuel flow meter that monitors both fuel-flow rate, which is limited to 100kg/h, and the overall fuel usage, which is limited to 100kg per race.

The FIA has asked for these systems to be implemented by the Chinese Grand Prix in April at the latest. But it has also requested that teams do so earlier if possible, with each team set to be contacted by the FIA to evaluate how the fuel pressure will be measured and how these systems will fit in with the standard ECU. This will allow the FIA to monitor the fuel flow through the system in more depth rather than relying purely on the single FIA-homologated fuel-flow sensor that all cars must carry in their fuel tank.

This could potentially allow closer monitoring of technical regulation 5.10.5, which states that "any device, system or procedure the purpose and/or effect of which is to increase the flow rate after the measurement point is prohibited."
