Keep your pump system running correctly with a part that was built for the machine from the start.
Key Features
- OEM-Grade Hose Construction — Manufactured to Wacker Neuson's original material and dimensional spec, ensuring correct flow routing and pressure-compatible flexibility for the APT pump series.
- Direct-Fit Installation — Engineered to connect to the existing overflow port without modification, matching the original hose routing and end fittings on APT4S and APT4T models.
- Broad APT Series Coverage — Compatible with APT4S Pump with Skid, APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, and all Cold Weather variants across both series.
- Prevents Overflow Misrouting — A correctly installed overflow hose channels excess fluid safely away from sensitive pump components; a cracked or missing hose can cause fluid accumulation, contamination, and accelerated wear.
- Fuel System Integrity — Properly routing overflow discharge is essential for safe fuel system operation; using the correct OEM hose maintains the designed separation between overflow output and ignition or brake components.
The overflow hose in an APT series pump is responsible for safely channeling excess fuel or fluid away from the pump assembly when tank or system pressure exceeds normal operating levels. By directing overflow discharge to a controlled exit point, the hose prevents fluid from pooling near mechanical or electrical components where it could cause damage or create a hazard. When the hose cracks, collapses, or loses its seal at either end, overflow fluid can migrate into unintended areas of the machine, leading to component contamination and potentially unsafe operating conditions.
