Q How rugged are Marine Flexible Auxiliary collapsible fuel Tanks?
A. Quite. They are constructed of rubberized ballistic nylon as used in military Flex-Tanks of 20,000 and 50,000 gallon capacity.  Nevertheless, all bladders should be handled with normal care and respect, especially when filled with flammable fuel.
Q What size bladder fuel tanks are available?
A In gallons:  25, 50, 75, 100, 150, 200, 300. 500
In liters: 100,  200, 300, 400, 600, 800, 1200.
 Custom size tank and shapes are available on special order.
Q Is there a bottom fuel outlet?
A No, the bladder outlet is about at “equator” height and “floats” downward as fuel is drained and the bladder collapses.
Q Can I connect the tank directly to my engine?
A The bladders are intended as auxiliary tanks rather than as main tanks. However, once secured,  bladder tanks  have been used to directly supply those gasoline engines which do NOT require a fuel return line. Diesel engines commonly DO require a return line and therefore should NOT be fed directly from a bladder tank we can provide special fuel bladders for direct diesel connection. .
Q Can I get every drop out of the tank?
A Nearly. For full purging,  may be rolled up from its far corner toward the outlet fitting.
Q How is fuel transferred to the main tank?
A Attach a ½” inside diameter hose (12mm) to the barbed outlet fitting, and run this hose as far down the main fuel tank inlet pipe as possible. Open the ball valve and press firmly on the tank to initiate gravity of siphon flow. Be careful not to overfill the main tank.
 
Q How do I tie down a full collapsible Marine bladder tank?
A Our Range Extenders are best transported either full or empty. Empty tank should be collapsed and stored in a vented locker. Full tanks should be lashed down with a cargo net or with one of our Tie-Down Kit harnesses.
 
Q When full, my tank seems very stable on deck, why do I need to tie it down?
A Under most conditions, a full tank will stay put, but in high seas (or turbulent air) bladders can become unstable and shift. With full weights of 150 lbs. to 1800 lbs., it is too dangerous not to use them fully restrained.
