SAMDO Universal Fuel Gauge Digital Fuel Level Gauge Marine Fuel Meter Full Waterproof Signal Adjustable 7 Color Backlight 52mm 12V/24V 0-190ohm, 240-33ohm, 240-30ohm, 0-180ohm, 10-180ohm

I installed this in my John Deere F932 lawn mower. JD wanted $150 for a factory one and used ones were around $90 online. The installation instructions for setting the resistance range were fairy easy to follow. I used my multimeter to measure the resistance range of my sending unit when empty and full (about 8 and 184 ohms in my case). So I selected the 10-180 ohm range. You press and hold the mode button for 3 seconds or so to put it into setup mode. The backlight will begin to flash. Then you press and release the mode button as needed until the needle points to the fill mark on the gauge that corresponds to the ohms range as illustrated in the instructions. In my case I had to press and release a couple times until the needle point to the half full mark, which corresponds to 10-180 ohms. Once set, power down the unit and you are done. It has like 6 different back light colors you can set as well, but I didn't mess with it. I left it the default red.

Gauge is easy to use, does have 7 color adjustment and signal adjustment abilities. Button is on the back so you need to set it before mounting it in but other than that works perfectly for my sim racing rig. Mine was missing the instructions but I figured it out. So far has been reliable under constant use and ohm variance. I suggest using it for the price.

I put this gauge in my boat. The great attribute for me was the adjustment for the different type of sending unit in the tanks. The factory that built my boat was un-sure of the type sensor that was installed into my boat from the factory. That can be adjusted by simply pressing a button. The instructions were easy to follow and the installation took less than 10 minutes.

Been search for one to match my sender and had to return a few. Then I found this one that you can set to any sender ohms! Blew my mine that this existed. Hooked it up and it works great! Easy to install and directions were easy.Thank goodness!

Very easy to mount, with large nut on backside, and simple to choose background color and to match ohm range of sending unit. Only downside is: 1) gauge depth requires more space on backside then most. 2) program button is on back of gauge, so need to have access.

Needed a Fuel gauge to match three other existing black-faced gauges. It is a 1/32 larger than 2" diameter, but it comes with a rubber O-ring to seal. It is analog in design, not digital. Comes with the wires built right into the gauge. The installation was very easy due to the threaded outer surface and the hand tightening plastic nut.

It reading full tank when it's only quarter of a tank . I pressed and hold for 3s and it's zeroed than press to match qurtare of a tank but it always go to full tank . Any suggestions ? Thxx

Works well in golf cart highly adaptable for color and sending unit
