Each marine fuel bladder includes:
✔ Marine Fuel Bladder
✔ Protective Storage Liner
✔ 1/2" Fuel Valve
✔ Carry / Storage Bag
✔ 10 ft Fuel Discharge Hose (3/8" ID)

Features and further details of our New Gen 7 Bladders
Every time you get on your boat or yacht, one of the first things on your mind is fuel. Whether you've planned a day of water sports, you're heading out to the ocean for diving or fishing, or you're taking off on a long voyage, having reliable extra fuel is always beneficial.
Don’t let an empty fuel tank spoil your fun—and don’t be a victim of poor-quality fuel or ultra-high prices. A marine fuel bladder is a great solution for extending your vessel’s range. These bladders are designed to occupy minimal space when not in use and can be stored in a compartment to free up deck space.

Testimonials
"This bladder paid for itself on my first trip to the Bahamas. Fuel there was so expensive I couldn't believe it."
"I had major engine damage caused by bad fuel. Since I got my Techno Tanks bladders, I have enough fuel for my trips, so I never have to fill up at shady places."
"Our family is big on water sports, and there's nothing more annoying than having to stop the fun to take the boat out of the lake for a refill in town. Now we have two bladders—one in the boat and one filled in the boathouse. Fuel stopped being an issue!"
