Installation Guide

  1. Safety First: Disconnect the battery and ensure the engine is cool. Work in a well-ventilated area and have a fire extinguisher nearby.
  2. Locate Pump: Find the existing mechanical fuel pump on the engine block.
  3. Disconnect Lines: Place a rag under the connections to catch fuel. Carefully disconnect the inlet, outlet, and vent tube fuel lines.
  4. Remove Old Pump: Unbolt the old pump from the engine block and remove it along with the old gasket.
  5. Clean Surface: Clean the mounting surface on the engine block to ensure a good seal with the new gasket.
  6. Install New Pump: Place the new gasket, then install the new fuel pump. Tighten the mounting bolts to the manufacturer's specified torque.
  7. Reconnect Lines: Securely attach the inlet, outlet, and vent tube lines to the new pump.
  8. Check for Leaks: Reconnect the battery. Prime the fuel system and start the engine. Carefully inspect all connections for any signs of fuel leaks.
