Safety Information
Always prioritize safety when working with fuel systems. Fuel is highly flammable and its vapors are explosive. Failure to follow these safety precautions can result in serious injury or death.
- Ensure the engine is cool and turned off before beginning any work.
- Disconnect the spark plug wire to prevent accidental starting.
- Work in a well-ventilated area, away from open flames, sparks, or other ignition sources.
- Wear appropriate personal protective equipment, including safety glasses and gloves.
- Have a fire extinguisher readily available.
- Properly dispose of any spilled fuel or old fuel lines according to local regulations.
Setup and Installation
This section outlines the steps for replacing your fuel line. The Briggs & Stratton 791766 fuel line is supplied as a length of hose with two clamps.
Tools Required:
- Pliers (for hose clamps)
- Utility knife or sharp scissors (for cutting fuel line)
- Container for draining fuel
- Shop rags
Installation Steps:
- Prepare the Engine: Ensure the engine is off and cool. Disconnect the spark plug wire.
- Drain Fuel: If possible, drain the fuel tank into an approved container. If not, pinch off the fuel line to minimize spillage.
- Remove Old Fuel Line: Use pliers to loosen and remove the existing clamps from both ends of the old fuel line. Carefully pull the old fuel line off the carburetor and fuel tank/filter connections. Be prepared for some fuel spillage.
- Inspect Connections: Check the carburetor and fuel tank/filter connections for any debris or damage. Clean if necessary.
- Measure and Cut New Fuel Line: Hold the new Briggs & Stratton 791766 fuel line next to the old one to determine the correct length. Cut the new fuel line to match the length of the old one using a utility knife or sharp scissors. Ensure cuts are clean and straight.
- Install New Clamps: Slide the new clamps onto each end of the new fuel line.
- Connect New Fuel Line: Carefully push one end of the new fuel line onto the fuel tank/filter connection and the other end onto the carburetor connection. Ensure the line is fully seated on both connections.
- Secure Clamps: Position the clamps over the connections and use pliers to tighten them securely. Ensure a tight seal to prevent leaks.
- Final Checks: Reconnect the spark plug wire. Refill the fuel tank. Inspect all connections for any signs of leaks. Start the engine and observe for any fuel leaks during operation.

Operating Considerations
After installation, ensure the fuel line is not kinked or pinched by other engine components. Proper routing prevents premature wear and ensures consistent fuel flow to the engine. Regularly check the fuel line for any signs of wear or damage before each use of the equipment.
Maintenance
To prolong the life of your Briggs & Stratton fuel line and ensure safe operation, consider the following maintenance tips:
- Regular Inspection: Periodically inspect the fuel line for cracks, hardening, swelling, or any signs of fuel leakage. Replace immediately if any damage is observed.
- Proper Storage: When storing equipment for extended periods, especially during off-season, ensure the fuel system is properly prepared according to your engine's manual. This often involves draining fuel or using a fuel stabilizer.
- Avoid Kinks: Ensure the fuel line is routed without sharp bends or kinks that could restrict fuel flow or cause stress on the material.
- Cleanliness: Keep the area around the fuel line clean and free of debris that could abrade or damage the line.
Troubleshooting
If you experience issues after replacing the fuel line, consider these common troubleshooting steps:
- Fuel Leaks:
- Check that clamps are securely tightened at both ends of the fuel line.
- Ensure the fuel line is fully seated on the carburetor and fuel tank/filter connections.
- Inspect the fuel line for any cuts or punctures that may have occurred during installation.
- Engine Not Starting or Running Poorly:
- Verify that the fuel line is not kinked or pinched, restricting fuel flow.
- Ensure there is adequate fuel in the tank.
- Check for proper connection of the spark plug wire.
- If the issue persists, consult your engine's specific service manual or a qualified technician.
