Fuel Safe's marine fuel bladders are designed to safely transport liquids, specifically for ocean going vessels and race boats, however they can be used for all forms of liquid transport. The line of auxiliary fuel bladder tanks we offer allows sport-fishing vessels, recreational yachts and work boats to carry an additional 25-1000 gallons of fuel on board in a convenient flexible bladder that folds up and stows away when not in use. Fuel Safe’s marine fuel bladders are the most popular collapsible boat tanks on the market due to their durability and quality.

"I’m very pleased with this bladder. Even though I didn’t need it for the crossing, I used it extensively on the trip. It extended my range and reduced the number of fuel stops as a result. Works great."
