Primer pumps, and flexible pipes and hoses

In Simple Terms

This rule covers the fuel system components that help get fuel from the tank to the engine, specifically the primer pump (which pressurizes fuel), the pipes and hoses connecting these parts, and the sensors that monitor fuel flow, pressure, and temperature. Teams must use FIA-approved equipment and proper connections between the pump, breakaway valve, and fuel flow meter.

• Primer pump is required to pressurize and circulate fuel in the system
• All flexible pipes and hoses must have proper fittings and be securely connected
• Fuel flow meter inlet sensors for pressure and temperature must be correctly positioned
• Equipment must meet FIA specifications for safety and measurement accuracy
