Fuel Oil, Diesel Oil, DEF or Water Tank Gauge German Made 1 1/2" 40" to 44"

Easy to install, highly visible, works as advertised.

I like the float mechanism which operates the gauge. I did have to buy a 2" to 1 1/2" adapter which added another $18 to the project, but installation was straight forward. The plastic constructions seems pretty sturdy, but I wonder, over time, how exposure to the elements will impact the plastic. I guess we shall see. But this sure beats using stick to determine how much oil is left in the tank!

easy to read
