Safety First: Always ensure the engine is off and cool before attempting any maintenance. Disconnect the battery if necessary. Wear appropriate safety gear, including eye protection and gloves. Be prepared for fuel spills and have absorbent materials ready.
- Locate the Existing Fuel Filter: Refer to your equipment's service manual to identify the location of the fuel filter. It is typically found in the fuel line between the fuel tank and the carburetor/fuel pump.
- Prepare for Removal: Place a suitable container beneath the fuel filter to catch any spilled fuel. Use clamps or pliers to pinch off the fuel lines on both sides of the filter to minimize leakage.
- Remove Old Filter: Carefully disconnect the fuel lines from the old filter. Note the direction of fuel flow (usually indicated by an arrow on the filter) to ensure the new filter is installed correctly. Remove the old filter.
- Install New Filter: Orient the new Shanrya Fuel Filter according to the fuel flow direction. Connect the fuel lines securely to the inlet and outlet ports of the new filter. Ensure all connections are tight to prevent leaks.
- Check for Leaks: Remove the clamps from the fuel lines. Start the engine and allow it to run for a few minutes. Carefully inspect all connections around the new fuel filter for any signs of fuel leakage. Address any leaks immediately.
- Dispose of Old Filter: Dispose of the old fuel filter and any spilled fuel according to local environmental regulations.
