Frequently Asked Questions

They are extremely resistant as they are manufactured with military specs and materials. However, we recommend that all tanks be handled with care and respect, especially when filled with flammable fuels.

Sizes available are for 30, 60, 80, 100, 150, 200 & 250 gallons. Custom sizes and shapes are available on special order.

The tanks can be connected directly to the engines as long as you are using the correct fittings and adapters.

Almost all the fuel will be purged. You can aid the process by rolling the tank from the outside towards the outlet fitting.

Techno Tanks bladder tanks are best transported either full or empty. Empty bladders should be collapsed and stored in a vented locker. Full bladders can be tied down to the deck by using the rings located on the top of the tanks.

Under most conditions, a full bladder tank will stay put, but in high seas (or turbulent air) bladders can become unstable and shift. With full weights of 150 lbs. to 3000 lbs., it is dangerous to use them if not fully restrained.

Coast Guard regulations do not permit in-hull locations. We recommends securely lashing the full bladder above deck for better gravity fuel transfer, safer venting and ease of clean-up should any fuel be spilled during filling.

Yes, to some extent. Despite UV additives and hydrolysis stabilizers, rubber and fabric products can take a beating in extremes of sun, cold, dampness and abrasion.  When not in use, we recommend storing the drained bladder in a dry and vented locker.

No, we recommends gravity or siphon flow, but Reverso and Jabsco can provide 12V and 24V diesel pumps with explosion-proof motors. Arnold offers a hand siphon pump.

No. Full bladders are very hard to grasp and they weigh from 150 to 3000 lbs. We recommend filling them located were they will be used.

Yes, definitely! Fuel is 2/3 the density of water so it will always produce buoyancy. Also, in emergencies, an empty bladder can be lightly filled with air to provide significant buoyancy for personnel and the entire craft.

How about some extra fuel for those longer trips?
