When can a fuel tank be recertified for another two years?
On the fuel tank certificate, issued at the time of purchase, you will find the date of manufacture (1. MANUFACTURED ON) and the expiration date of the validity, also stated on the tank label (2. NOT VALID AFTER). Five years following the date of manufacture the tank is no longer valid and cannot be admitted to FIA-regulated competitions.
However, as per FIA regulation, you can ask ONLY the manufacturer of the fuel tank who issued the relative certificate for an extension of validity for a further two years.
1. MANUFACTURED ON: the validity expiry date, also stated on the fuel tank label.
2. NOT VALID AFTER: five years after the production date, the fuel tank is no longer valid and cannot be admitted to FIA-regulated competitions.
