4. Installation Instructions
Follow these steps to replace the primer bulb and fuel lines. Specific procedures may vary slightly depending on your tool model.
4.1 Replacing the Primer Bulb
- Locate the Primer Bulb: Identify the existing primer bulb on your carburetor or engine housing.
- Disconnect Fuel Lines: Carefully pull off the fuel lines connected to the old primer bulb. Note which line connects to which nipple (typically one shorter, one longer). If lines are stiff, a hair dryer can be used to gently warm them for easier removal.
- Remove Old Bulb: The primer bulb is usually held in place by two clasps. Gently pry these clasps to release the old bulb.
- Install New Bulb: Insert the new HURI primer bulb into the opening, ensuring the clasps snap securely into place.
- Reconnect Fuel Lines: Attach the fuel lines to the corresponding nipples on the new primer bulb. The shorter nipple typically connects to the fuel tank, and the longer nipple connects to the carburetor. If the fuel lines are difficult to attach, gently warm them with a hair dryer to make them more pliable.
4.2 Replacing Fuel Lines
If your existing fuel lines are cracked, brittle, or leaking, they should also be replaced.
- Identify Lines: Trace the fuel lines from the primer bulb/carburetor to the fuel tank. Note their routing and connections.
- Remove Old Lines: Carefully disconnect the old fuel lines from all connection points (primer bulb, carburetor, fuel filter in tank).
- Cut New Lines: Using the old lines as a guide, cut the new HURI fuel line tubing to the appropriate lengths. Ensure clean, straight cuts.
- Install New Lines: Route the new fuel lines in the same manner as the old ones. Connect them securely to the primer bulb, carburetor, and fuel filter. Ensure all connections are snug to prevent leaks.

5. Operating Instructions (After Installation)
After replacing the primer bulb and fuel lines, it is crucial to prime the fuel system before attempting to start the engine.
- Fill Fuel Tank: Ensure the fuel tank contains fresh, appropriate fuel for your power tool.
- Prime the System: Press the primer bulb repeatedly (typically 5-10 times) until you see fuel flowing into the bulb and returning to the fuel tank. The bulb should feel firm.
- Start Engine: Follow your power tool's specific starting procedure.
6. Maintenance
Regular inspection and maintenance can extend the life of your fuel system components.
- Inspect Regularly: Periodically check the primer bulb and fuel lines for cracks, hardening, or signs of leakage.
- Clean: Keep the area around the primer bulb and fuel lines free of dirt and debris.
- Proper Fuel: Always use the correct fuel mixture (if applicable) and fresh fuel to prevent damage to fuel system components.
- Storage: When storing your tool for extended periods, drain the fuel system or use a fuel stabilizer to prevent fuel degradation.
7. Troubleshooting
If you encounter issues after installation, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine won't start / No fuel in primer bulb | Clogged fuel filter, kinked fuel line, incorrect fuel line connection, air leak. | Check fuel filter for clogs and replace if necessary. Ensure fuel lines are not kinked and are connected correctly. Verify all connections are tight. |
| Fuel leak around primer bulb or lines | Loose connections, damaged primer bulb, cracked fuel line. | Tighten all fuel line connections. Inspect primer bulb for cracks; replace if damaged. Inspect fuel lines for cracks; replace if damaged. |
