After installing the fuel pump in the fuel tank and fabricating the fuel regulator/filter assembly I bolted it all into place. A vacuum line runs from the engine back to the regulator. I fabricated the floor over the tank, made a partition to separate the battery, and made panels to cover the taillight area. Then carpet was laid down. I added a wire lead to extend under bumper to both charge the battery via a float charger while in storage or the apply 12 volts to the system to unlock doors.
