Fuel Tank Problem
 It is almost impossible to fuel the auto due to the collapse of the fuel bladder.  I understand this is a problem only in cold weather.  Maybe someone will find a solution to this. Would pressurizing this tank with about 5 psi of air pressure prior to refueling expand the bladder to normal size?
