370Z Fuel Gauge?!?!

SoCal 370Z · 04-23-2009, 11:53 AM

I haven't actually remove the fuel tank, and doubt that I will, but in studying the iso there appears to be no crossover tube for the two-sides of the fuel tank. Since the tank sits atop the drive shaft (why oh why didn't Nissan make the 370Z FWD

) the tank actually has two sides to it. On other vehicles this has presented a problem with misreading fuel gauges. There are two fuel gauge sensors in the fuel tank.

Men generally have bad color-related visual acuity and that gauge style is REALLY dependent on your ability to differentiate colors. I got lucky and have ninja-like color recognition and the gauge doesn't bother me at all.

Just wanted to re-iterate with everyone that those segments are NOT LEDs, you're really looking at a plastic lens. Each segment is actually part of the entire LCD display. The only LEDs is the amber backlight.

Therefore, changing the LCD display backlight will change the Fuel/Temp indicator colors as well.

If the segments were LED, an off indicator status will be virtually pitch black. However, off has the same darkness as the LCD, itself.

As with previous experience with the 350Z gauge cluster, there is a thin piece of plastic filter with yellow coloring. Underneath is at least 6 amber LEDs. You'll need to file down the yellow coloring, and the filter plastic becomes opaque white. Then you can change the backlight color to anything you want. In my case, it was white. The display segments light up white, while the dark portions show up blue.

Example:

So if I change the backlight to white, the Fuel/Temp "off" segments will show up blue. The "on" segments will be white.
