2021-01-01 - Extra Fuel Capacity

Q.
My question is if you have a vehicle with 11 gallon stock tank and you put a 18gal fuel cell in the car what would the penalty be for the extra fuel ?
Looking at building a new car but the stock tank is 11 gallon and wanting to add a fuel cell to get in the fuel range as most the other competitors.

A.
You can NOT add fuel capacity.  It would be an immediate disqualification or move to the EC class.

You could run our EC class as the fuel capacity is not regulated for EC.
