Stock marine fuel tanks are fuel tanks for boats and other sea-worthy vehicles. These are the fuel tanks that the boat manufacturers put on their vehicles, either above or below deck, and are typically cheaper than custom models and fit a majority of industry standard water vehicles.
Stock marine fuel tanks cost anywhere from approximately $155 to $670, depending on desired size, material used and gallon capacity. The most common fuel tank is for below deck, with above deck fuel tanks being smaller and portable for ease of use. Stock marine fuel tanks are most commonly made from industrial plastic or aluminum to eliminate risk of rust.
