With plastic tail tanks bladders are required, however unlike Fuel thirsty midgets on Methanol we start the Main with about 5 gallons of methanol, guys on gasoline use about 2 1/2 to 3 gallons, so provisions are made for small drag strip style fuel cells mounted under a fiberglass tail section. It's kinda of weird sticking that fuel stick down inside that bladder beneath the baffle looking for the fuel level. We like the tail tank so we use a bladder, while I feel like the guys with a 6 gallon drag style fuel sell mounted securely are just as safe in an accident.
