All New Design 49L (13 US Gallon) - Long Range Auxiliary Fuel Tank – Sea-Doo ST3 Hull
Extend your adventures and explore further with our all-new 49L Auxiliary Fuel Tank, purpose-built for Sea-Doo ST3 Platform models.
Manufactured from high-grade XLPE Polyethylene, this tank significantly increases your total fuel capacity while maintaining safety, balance, and a clean factory-style appearance. Designed to integrate seamlessly into your craft, it mounts securely using dedicated brackets with no compromise to storage space or rider comfort.
Why struggle with multiple bulky jerry cans strapped to the rear? They’re heavy, awkward to handle, prone to spills, can introduce water contamination, and dramatically affect the ride quality and handling of your Sea-Doo by placing unnecessary weight where you least want it.
✅ No need to stop and refuel manually – Enjoy uninterrupted rides.
✅ DIY installation
✅ Material: XLPE Polyethylene
✅Internal Capacity: 49 liters or 12.95 US Gallons ( Typically fills to 47 liters)
✅ The tank integrates directly into your OEM fuel system and operates via a simple, reliable gravity-fed design (not a siphon or vacuum-style setup) As fuel is consumed from the main tank, the auxiliary tank naturally replenishes it, venting through either the OEM filler neck or its own dedicated filler. While fuel remains in the auxiliary tank, your fuel gauge will continue to display full. Once the gauge begins to drop, this indicates the auxiliary tank has been depleted and you are now drawing from the remaining fuel in the main tank.
✅ Compatibility: Sea-Doo ST3 platform (2018–present)
Stop cutting your rides short. Equip your Sea-Doo with the range it deserves and ride with confidence.
Y-Junction Filler
This setup connects directly into the OEM filler location by shortening the factory filler hose to create the required space for a Y-junction, with a separate filler hose routed to the auxiliary tank. It is the same proven system used on our earlier-generation aluminium tanks. When refuelling, one side of the junction is used to fill the main tank first, while the other side allows you to direct fuel into the auxiliary tank. With no external cap and no visible cosmetic modifications, it delivers a clean, seamless factory-style appearance. Refuelling remains simple through the standard filler point.
