Sensor Plate Lever Adjustment

  1. With fuel distributor removed from airflow sensor housing, measure distance between roller on sensor plate lever and contact points of fuel distributor on top of the airflow sensor housing. See Figure.
  2. Use a depth gauge or vernier caliper for measuring distance. Distance should be .74-.75" (18.9-19.1 mm). If distance is out of specified range, correct it by adjusting mixture screw.
  3. Lightly lubricate new sealing "O" ring with fuel and mount on fuel distributor. Install fuel distributor. See TORQUE SPECIFICATIONS  table. Connect all fuel lines except those to fuel injectors. Check sensor plate adjusting lever and fuel distributor control piston for smooth operation.
  4. Remove fuel pump relay and jumper fuel pump circuit. Use Jumper Switch (US 4480/3) in place of fuel pump relay. When pressure has built up, turn off fuel pump. Move sensor plate from rest position to end of travel.
  5. Uniform resistance should be felt during entire movement. No resistance should be felt on quick return to rest position. Connect injector lines. Install fuel pump relay. Start engine and check for leaks.
