A fill tube for an oil tank may have at least one baffle coupled to an inner wall of the fill tube. A first baffle may have an aperture. A release tube may be coupled to the baffle at the aperture. An object may be inserted through the aperture. The object may force open a flapper valve coupled to the fill tube. Pressure in the oil tank may be released through the flapper valve. The baffles may prevent hot oil from spraying out of the fill tube. After the pressure has been equalized, oil may be poured into the fill tube to fill the oil tank.
