RESTRICTOR FIA

The FIA Refuelling Restrictor is a critical component in regulated motorsport fuel systems, designed to control the flow rate of fuel during pit stops in accordance with FIA standards. This restrictor helps ensure both fairness and safety in competition by managing refuelling times across all teams. The standard version is machined with a 33 mm internal diameter, making it suitable for most series-approved applications. For teams competing under different regulations or with unique refuelling requirements, custom diameters are available on request, ensuring full compliance with series-specific rules.

NOTE:
Custom restrictor diameters (XX mm) available on demand. Please specify your required size during finalization of the order.
