Taina sells duty free fuel but you need to come into the fule dock with the boat. Does not sell DF in jerry jugs. Gasoline or petrol is not sold duty free.
Phil confirmed that they do not sell duty free fuel on the weekend. They are too busy with locals fueling up to mess around with the duty free paperwork.
In an "emergency" they will sell duty free, but they are not keen to do so. The fuel dock hours are 0630-1200, 1300-1600.
