The Powr 103-842A Siphon Hose Assembly is a critical fluid intake component that delivers paint from the container to the pump on PowrLiner 2850 models. It consists of a durable, flexible hose and a rigid pickup tube fitted with a strainer to block debris that could clog the pump or spray tip.
Over time, hoses can become cracked, brittle, or develop pinhole leaks from exposure to solvents and repeated flexing. A damaged siphon hose may cause air ingestion, loss of prime, or erratic spray pressure. Replacing it with this OEM assembly restores reliable fluid pickup and helps maintain consistent spraying performance.
| Fluid delivery | Transfers paint from the container to the pump inlet |
|---|---|
| Debris filtration | Integrated strainer traps particles that could damage pump or tip |
| Prime maintenance | Helps the pump stay primed by providing an airtight path |
| Cracks / leaks | Visible damage causing air ingestion or drips |
|---|---|
| Hardening / stiffness | Loss of flexibility, making hose difficult to position or prone to kinking |
| Clogged strainer | Debris buildup that cannot be cleaned, restricting flow |
| Loss of prime | Pump repeatedly loses prime; hose is suspected as the cause |
Powr part 103-842A is specifically designed for the PowrLiner 2850 airless sprayer. Always confirm fitment by consulting your machine’s parts manual.

When replacing the siphon hose, inspect these associated fluid intake components to ensure complete system reliability.
Debris that passes a damaged siphon strainer can clog the inlet valve; clean or replace as needed.
Air leaks from a cracked hose can cause the pump to run dry, accelerating packing wear.
If debris enters the system, the main fluid filter may be clogged; check and clean it.
