Product Details
Product Details
The FB40MB solves a common problem: how do you carry more fuel when space is tight? By stacking two 20L bladders and permanently bonding them with high-strength HF and hot-air overlap welds, the FB40MB delivers a full 40L of capacity in a flexible, corner-friendly form factor. Those same welds allow fuel to flow freely between the upper and lower chambers, so the two sections work as one seamless unit.
Filling is simple — fuel goes in through the inlet on the top bladder and is drawn out through the outlet on the lower bladder. Eyelets around the top bladder let you strap it securely to a deck, trailer, or roof rack. And as your fuel level drops, the bladder collapses with it, shrinking down for clean, compact storage when empty.
Built from heavy-duty reinforced fuel-grade TPU, the FB40MB is engineered to handle whatever Australia throws at it — UV, vibration, salt air, corrugated dirt roads, and everything in between.
Ideal for:
• Small boats & RIBs
• Marine backup fuel storage
• 4WD touring & off-road vehicles
• Remote expeditions where rigid tanks won't fit
