Installation Notes

1. Safety First: Before starting, disconnect the battery and ensure the engine is cool. Work in a well-ventilated area and have a fire extinguisher nearby.
2. Locate and Disconnect: Find the old fuel pump on the engine block. Place a rag underneath to catch any spilled fuel. Carefully disconnect the fuel lines and hose clamps.
3. Remove the Old Pump: Unbolt the existing fuel pump from the engine. Note the orientation of the fittings and mounting bolts.
4. Clean the Surface: Clean the mounting surface on the engine, removing any old gasket material or sealant to ensure a proper seal.
5. Install the New Pump: Position the new gasket and fuel pump. Hand-tighten the mounting bolts, then torque them to the manufacturer's specifications.
6. Reconnect Lines: Attach the fuel inlet and outlet lines to the new pump, securing them with the original clamps. Ensure they are snug and leak-free.
7. Test the System: Reconnect the battery. Prime the fuel system if necessary. Start the engine and carefully check for any fuel leaks around the pump and fittings. Let the engine run for a few minutes to confirm proper operation.
