The Wacker Neuson Fuel Tank is a genuine OEM component designed for the GP3800A, GP5600A, GP6600A, GPS5600A, and GPS6600A series portable generators. As a factory-sourced part, it meets the exact dimensional and material specifications of the original, ensuring a direct, trouble-free installation. This fuel tank is confirmed to fit both EPA and CSA configurations across the GP and GPS generator families, with and without wheel kits. If your generator is losing fuel, running lean, or showing signs of tank damage or deterioration, part number is the correct OEM replacement to restore full operation.
Key Features
- OEM-Grade Fuel Compatibility — Manufactured to the same material and capacity specifications as the original tank, ensuring proper fuel storage and feed without seepage or degradation.
- Direct-Fit Installation — Matches original mounting points, fuel outlet fittings, and cap interface on the GP and GPS generator frames for a straightforward swap with no fabrication needed.
- Broad Generator Family Coverage — Fits GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, and GPS6600A models across EPA and CSA variants, including wheel-kit configurations.
- Consistent Fuel Delivery — A structurally sound, properly sealed tank maintains steady fuel flow to the engine, supporting stable output and preventing surging or unexpected shutdowns under load.
- Fuel System Safety — A compromised tank risks fuel leaks that create fire hazards on the jobsite; replacing it with a genuine OEM unit restores the sealed, certified fuel containment the generator was engineered around.
The fuel tank stores the gasoline supply that feeds the generator's engine and acts as the foundation of the entire fuel delivery system. It must maintain a reliable, leak-free seal under varying temperature and vibration conditions to ensure consistent engine operation. When a tank cracks, warps, or develops a faulty seal, fuel starvation, leaks, or unsafe operating conditions can follow — making timely replacement critical to both performance and site safety.
