The Wacker Neuson Fuel Tank is a genuine OEM component designed for the HI 300HD D and HI 400HD D indirect-fired diesel air heaters. Sourced directly from Wacker Neuson, this fuel tank matches the original equipment specification — ensuring proper fitment, correct capacity, and compatibility with the fuel delivery system on these heavy-duty heating units. As a genuine OEM part, it carries the same design and material standards as the tank installed at the factory, so you can restore your heater to full working condition with confidence. Whether you're replacing a cracked, leaking, or damaged tank, part number is the correct replacement for these HI-series diesel heaters.
Key Features
- OEM-Grade Fuel Containment: — Manufactured to Wacker Neuson's original material and dimensional standards, ensuring the tank resists diesel fuel degradation and maintains structural integrity under field conditions.
- Drop-In Fitment: — Engineered to align with the existing mounting points, fuel lines, and connections on the HI 300HD D and HI 400HD D, so installation follows the original service procedure without adaptation.
- Correct Fuel Capacity: — Matches the original tank volume, preserving the heater's rated burn time and runtime between refuels as intended by the manufacturer.
- Covers HI 300HD D and HI 400HD D Heaters: — A single part number spans both heavy-duty diesel indirect air heater models, making 5000183938 a reliable stocking choice for fleet operators and service technicians.
- Fuel System Integrity: — A sound, properly fitted fuel tank is essential for consistent fuel delivery to the burner. A cracked or leaking tank disrupts combustion performance and creates a fire and spill hazard on the job site.
- Safety-Critical Fuel System Component: — Fuel containment is a direct safety consideration on diesel-fired heaters; using the correct OEM tank eliminates the risk of fitment gaps, improper sealing, or incompatible materials that can cause leaks.
The fuel tank stores and supplies diesel fuel to the burner assembly of the indirect-fired air heater, acting as the primary reservoir that feeds the combustion system during operation. On diesel indirect heaters like the HI 300HD D and HI 400HD D, a sealed, intact fuel tank is critical — any leak or structural failure starves the burner of fuel, causes inconsistent heat output, or creates a fuel spill hazard. When the tank cracks, corrodes, or develops a leak, replacing it promptly with the correct OEM part restores safe, uninterrupted heating performance.
