FB20MB 20L Collapsible Triangular Fuel Bladder
The FB20MB's triangular pillow shape is designed to do what rigid tanks can't: slip into corners and awkward spaces on small boats, 4WDs, and trailers, turning wasted space into usable fuel capacity. Whether you're extending your range on the water or heading deep into the outback, the FB20MB gives you the extra fuel you need without taking up more room than necessary.
Filling is straightforward — fuel goes in through the 1¼" (32 mm) poly inlet fitting and is dispensed via the ½" (13 mm) poly BSP male outlet. Three reinforced eyelets on each side keep the bladder firmly secured during transit and operation, while the built-in carry handle makes moving it between vehicles or vessels easy. When the tank runs dry, it collapses flat and stows away cleanly until next time.
Built from heavy-duty 1,200 GSM reinforced TPU, the FB20MB is fuel-resistant, UV-stable, and engineered to handle the vibration, salt air, and rugged conditions that come with Australian marine and off-road adventures.
Backed by a 2-year manufacturer warranty.
