The Wacker Neuson 5200021670 is a genuine OEM Fuel Suction Hose Complete designed for APT6T and APT6S series pumps, including Electric Brake, Surge Brake, Skid-mounted, and Cold Weather configurations. As a factory-sourced component, the 5200021670 meets the exact material and dimensional specifications set by Wacker Neuson, ensuring a direct, trouble-free installation. This hose assembly is confirmed to fit the full APT6T and APT6S lineup, covering both standard and Cold Weather variants across all brake configurations. Keeping the fuel delivery circuit in top condition is essential to maintaining consistent pump output and engine reliability on the jobsite.
Key Features
- Fuel-Grade Hose Construction — Built from materials rated for continuous contact with diesel fuel, resisting swelling, cracking, and degradation that can lead to fuel leaks or flow restriction.
- Complete Assembly — Supplied as a complete hose assembly, so all fittings and connections are pre-configured for a straightforward swap with no additional parts to source separately.
- Broad APT6 Series Coverage — Fits APT6T (Electric Brake and Surge Brake) and APT6S (Skid-mounted) models, including Cold Weather variants, covering the full APT6 pump family.
- Consistent Fuel Delivery — A sound suction hose maintains steady fuel draw to the engine; a cracked or collapsed hose causes lean running, hard starting, or engine shutdown under load.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this component carries the same part number and specification used on the original production line.
The fuel suction hose draws fuel from the tank and delivers it to the engine's fuel system under suction created by the fuel pump or lift pump. Because this hose operates under negative pressure, any crack, pinhole, or loose fitting introduces air into the fuel circuit, which disrupts the fuel-to-air ratio and can cause rough running, loss of power, or the engine to cut out entirely. Replacing a worn or damaged fuel suction hose promptly restores a sealed, uninterrupted fuel supply and keeps the pump engine running at full capacity.
