Description
Overview:
This Fuel Line Bushing is a Genuine Husqvarna part that seals the fuel line where it passes through the tank, helping to maintain correct fuel delivery and prevent leaks. Moulded from durable, fuel‐resistant rubber in a compact grommet form, it is designed for long service life with modern pump petrol, including blends containing ethanol. It fits a wide range of Husqvarna machines across disc cutters, brushcutters, hedge trimmers, chainsaws and riders, including the K970 disc cutter and 323HD60 hedge trimmer. A good seal at the tank is essential to avoid air ingress that can cause hard starting or lean running. Husqvarna part number 503 73 58‐01 (503735801).
Key Features:
- Genuine Husqvarna part for assured fit and compatibility across many models
- Fuel‐resistant rubber construction for durability and ethanol tolerance
- Provides a tight tank seal to help prevent fuel leaks and fumes
- Maintains steady fuel flow and helps avoid air leaks that affect performance
