| Q |
How rugged are ATL’s Petro-Flex Range-Extenders? |
| 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 fuels.
|
| Q |
What sizes are available? |
| A |
In gallons: 25, 50, 75, 100, 150, 200, 300.
In liters: 100, 200, 300, 400, 600, 800, 1200.
Custom sizes 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 Petro-Flex directly to my engine? |
| A |
Petro-Flex bladders are intended as auxiliary tanks rather than as main tanks. However, once secured, Petro-Flex bladders 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 Petro-Flex. ATL can provide special fuel bladders for direct diesel connection.

| Q |
Can I get every drop out of the bladder? |
| A |
Nearly. For full purging, the Petro-Flex 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 tank inlet pipe as possible. Open the ball valve and press firmly on the bladder to initiate gravity of siphon flow. Be careful not to overfill the main tank.

| Q |
How do I tie down a full Petro-Flex? |
| A |
ATL’s Range Extenders are best transported either full or empty. Empty bladders should be collapsed and stored in a vented locker. Full bladders should be lashed down with a cargo net or with one of ATL’s Tie-Down Kit harnesses.
|
| Q |
When full, my Petro-Flex seems very stable on deck, why do I need to tie it down? |
| A |
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 1800 lbs., it is too dangerous not to use them fully restrained.
|
| Q |
About how many Petro-Flex tanks has ATL produced? |
| A |
Since inception of the product, ATL has delivered approximately 20,000 of these bladders. To our knowledge, most are still in use.
