Remove Fuel Pump Module

  1. Follow the manufacturer’s instructions to gain access to the fuel pump module.
  2. Remove the firewall panels located behind the seats.
  3. Disconnect the power connector and crank the engine to bleed fuel pressure. Disconnect battery once the pressure has bled.
  4. Disconnect fuel line from the pump module. There will still be some fuel left in the fuel line.
  5. Remove the fuel pump ring and lift the module out of the tank (drain as much fuel back into the tank as possible).

    Figure 1: OEM Reference

Modify Fuel Pump Module for Return Line and Install Regulator Plug

  1. Place the 7/16” washer on the underside of the Top Hat and using a marker place a mark in the center of the washer. Use figure 2 as a reference for the return line location.

    Figure 2: Return Line Placement reference

  2. Start by drilling a 1/8” pilot hole on the mark that was made in the last step.
  3. From the top side of the top hat, drill a 7/16” hole. A Unibit is recommended but it is also possible to start with a smaller drill bit and step up to a 7/16” bit.
  4. Install the -4 bulkhead fitting using the stat-o-seal on the top of the top hat and the 7/16” washer on the bottom side. Use figure 3 as a reference for the orientation of the bulkhead fitting.

    Figure 3: Return Line reference

  5. Remove the metal clip that is retaining the factor regulator. Make note of the wire being held in place. Use figure 4 as reference.

    Figure 4: Metal Clip Reference.

  6. Use needle nose pliers to remove factory regulator.
  7. Press the supplied regulator plug into the housing.
  8. Reinstall metal clip making sure the clip is in contact with the bare wire.
  9. Clearance between the return line fitting and body panel is extremely tight. In order to help prevent the chance of rubbing, it is recommended that a portion of the body panel is removed. Use figures 5 and 6 for reference.
