FREQUENTLY ASKED QUESTIONS
How resistant are Techno Tanks bladders?
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.
What sizes are available?
Can I connect my bladder tank directly to my engine?
The tanks can be connected directly to the engines as long as you are using the correct fittings and adapters.
Can I get every drop out of the bladder?
Almost all the fuel will be purged. You can aid the process by rolling the tank from the outside towards the outlet fitting.
How do I tie down the bladder?
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.
My tank is stable when fuel. Do I still need to tie i down?
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.
Can I mount my fuel bladder below deck?
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.
Do the fuel bladders suffer from weather exposure?
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.
Do you offer an electric fuel pump for transferring gasoline or diesel?
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.
Can I fill the bladder with fuel and carry it to my boat?
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.
Will my bladder tank float if it falls overboard?
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.
