Installation Instructions

Before working on the fuel system, make sure the fuel system is NOT pressurized. Refer to the manufacturer’s instructions on how to depressurize the vehicle’s fuel system.

  1. Assemble the injector puller minus the threaded puller (fig. 1-2).
  2. Disconnect the injector wires, fuel lines and hold down clamps as per the manufacturer’s instructions.
  3. Install the threaded puller (fig. 3-2) onto the threads of the injector (hand tighten only).
  4. Slide the bridge assembly over the threaded puller (fig. 4-2), inserting the bridge support (fig. 4-3) onto the appropriate valve cover bolt (fig. 2-10) and into the injector clamp  bolt hole (fig. 2-11) for a sturdy footing.
  5. Torque the M8 bolt (fig. 4-5) to 15 ft. lbs.
  6. Install the threaded puller nut (fig. 4-4) onto the well lubricated threaded puller (fig. 4-2) until it is hand tight.
  7. Using the appropriate size wrench, tighten the threaded puller nut (fig. 3-2). The injector should gradually slide out. NOTE: An approximate force of NO MORE THAN 35 ft. lbs. should be applied to the threaded puller nut (fig. 3-2).
  8. If the injector cannot be removed, it may be necessary to use the suitable penetrating oil, and leave for a period of time before applying force again.
