Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact material and dimensional standards, ensuring the fuel tank assembly holds and seals properly under real working conditions.
- Complete Kit Format — Supplied as a full assembly kit, so all necessary components are included for a straightforward replacement without sourcing individual pieces separately.
- Correct Fit for the TANK4000 — Engineered specifically for the TANK4000 water tank, this kit mounts and connects to existing fittings without modification.
- Fuel System Integrity Restored — A worn or damaged fuel tank compromises the reliable fuel supply the engine needs to operate consistently; this kit restores that integrity in one service step.
- Fuel System Safety — A properly sealed and structurally sound fuel tank is essential for safe operation; using a genuine OEM kit ensures the assembly meets Husqvarna's design tolerances for containment and leak prevention.
The fuel tank on the TANK4000 water tank stores and supplies fuel to the engine that powers the unit's pressurized water delivery system. A cracked, deteriorated, or leaking fuel tank disrupts engine operation and creates a potential safety hazard on the worksite. Replacing the assembly with this OEM kit restores a secure, properly sealed fuel supply and returns the machine to correct operating condition.
