Wacker Neuson 5200012729 Fuel Tank 400 Gal, Tc, G320

The Wacker Neuson Fuel Tank 400 Gal, Tc, G320 is a genuine OEM component designed for the G320 Generator series, including the Cold Weather T4i and Custom T4i configurations. As a direct Wacker Neuson OEM part, the is manufactured to the exact specifications of the original tank, ensuring a correct, drop-in installation with no guesswork on fitment or connections. If your G320 generator is showing signs of a compromised fuel tank — such as fuel loss, contamination, or structural damage — this is the verified replacement to get your unit back in service.

Key Features

• OEM-Grade Fuel Containment: — Built to Wacker Neuson's original material and dimensional specifications, ensuring proper fuel retention, sealing integrity, and resistance to diesel fuel degradation over extended service life.
• 400-Gallon Capacity Maintained: — Replaces the original tank at full 400-gallon rated capacity, preserving the G320's extended run-time capability without compromise.
• Direct Fitment for G320 Generator: — Verified OEM fitment for the G320 Cold Weather T4i and G320 Custom T4i configurations; mounts and connects exactly as the original unit.
• Sustained Generator Output: — A sound, properly sealed fuel tank ensures consistent fuel delivery to the G320's engine, supporting uninterrupted power generation on the job. A failing or leaking tank can starve the engine of fuel or introduce contaminants that damage fuel system components.
• Fuel System Safety: — A structurally sound OEM replacement tank is critical for safe fuel storage and handling on a high-capacity portable generator; the 5200012729 meets the original design standards for containment and venting.

The fuel tank on the G320 generator serves as the primary on-board reservoir that stores and supplies diesel fuel to the engine throughout its operating cycle. At 400 gallons, this tank is engineered to support long, uninterrupted run cycles in demanding applications such as cold-weather operations or custom power generation setups. When a fuel tank cracks, corrodes, or develops a leak, it not only risks fuel loss and contamination but can also trigger engine starvation, unexpected shutdowns, and potential safety hazards — making prompt replacement with a genuine OEM part the right call.
