The new flush mount gauge assembly was then installed on the left side of the tank. There's a small metal tube that runs inside the tank from top to bottom to feed the gas gauge wire through the tank to the connector underneath.

Once the wiring was connected and hidden back under the tank, the ignition switch was turned to the "on" position, and LEDs lit up on the new gauge. Obviously as your gas level gets lower, fewer and fewer LEDs are lit. A photocell automatically adjusts brightness for improved visibility in sunlight and dims at night to avoid distraction. When turned off, all you see is the mirror chrome finish.

On the filler side, the pop-up cap was screwed in place. To help save your paint from the fuel nozzle, a chrome trim ring is provided in the kit. The kit simply sticks onto the tank with sticky tape.

A quick 1/2-twist and the filler cap pops up and can then easily be unscrewed.
