Works great!
Easy to wire in and fits a standard hole size. I set mine up so that the back light works whenever the genset is running. My fuel tank review has a photo of it.

Accurate and Customizable
Works great in my Sprinter to read both the fresh water tank and grey water tank. The reading on each tank is selectable through a single 3 position rocker switch ON>OFF>ON to power the gauge and select each tank signal. Some people stated they had problems understanding the programming since there are not instructions, so here they are: PROGRAMMING INSTRUCTIONS 1) Put the gauge in programming mode by pressing the black button on the back and hold it for 3 sec, or until the backlight flashes, then release. 2) Immediately press the button again to cycle through each of the available calibration options. Each push of the button moves the needle on the gauge from Empty to Full to indicate which range is selected. This programs the gauge to match the type of sensor you are using. Needle Position E - - - - - F E 0 ~ 190 ohms 1/4 0 ~ 180 ohms 1/2 10 ~ 180 ohms 3/4 240 ~ 33 ohms (The default setting from the factory is: 240 ~ 33 ohms.) F 240 ~ 30 ohms 3) Once the desired range is selected (by advancing the needle to one of the above ranges with each press), leave it alone and the gauge will timeout and go back into Operational mode. 4) In Operational mode each press of the button cycles through the selection of backlight colors available.

Good custom replacement
I have changed my entire speedometer pod in my 1970 Pontiac bonneville because the sweep needle broke, the gauge was 1 parts of 5 2" gauges I changed to make a whole new one. Works nice looks good, multi colors. I am happy with it.

Fuel Gauge
I like the light up function and color. However, this gauge seems to bounce around a lot. Could be an issue with my signal sender unit. But I ran out of gas on the side of the side of the road and my gauge said I had 1/4 of a tank.

Looks amazing. Doesn't work.
Does not work. Have tested the gauge by contacting black signal wire to ground and taking it away to both full resistance and no resistance and the gauge doesn't move but a tiny bit. Have tried all 4 modes by holding the mode button until it flashes the needle and short pressing mode to change between each of the 4 modes and allowing it to save setting and return to normal function.

I wired it as instructed, asked for help. Help didn't work. Brought boat to dealership, they could not get it to work. They installed another brand and problem solved. Nice looking gas gauge , can I return it? Real scam ,oh you are 5 days pass deadline to return it. How nice is that after asking for help 3-4 times.
