The fuel tank can have holes in it, but the total size of all openings can't exceed 35,000mm². Small circular holes (less than 35mm across) can be sealed with a fitting that's held down with a single bolt.

• Maximum combined aperture area in fuel bladder is 35,000mm²
• Small circular openings under 35mm diameter can use simple bolt-secured fittings
• Fittings must be secured with a single threaded fastener across the full opening diameter
• Prevents fuel leakage and ensures fuel system safety during races
