Effective immediately, and in order to ensure the safety of our drivers, vented fuel caps will not be allowed at Midwest Thunder events. This decision is based on significant fuel leaks that have been observed, videotaped, and reported over the past few weeks at our events, and also failures of the cap that have been communicated to us by other regions. Competitors will be expected to follow current Midwest Thunder rules regarding the fuel vent line: Fuel vent line must run out the left side of the car above the bottom frame rail, but no more than 1” above belly pan, must extend a minimum of 2” and be securely fastened.
