Husqvarna Part Number 545180870 is the OEM fuel tank assembly designed to replace worn or damaged tanks on compatible Husqvarna models and restore secure fuel storage and fitment.

This replacement is manufactured to Husqvarna’s specifications in the United States and intended for straightforward installation on the models listed by the brand. The part is an exact-design component rather than a generic aftermarket alternative, helping preserve the tool’s original layout and performance characteristics.

Which machines will this fuel tank assembly fit?

The 545180870 tank is made to match specific Husqvarna models that use the same mounting pattern, filler neck and fuel line routing.
