### ⭐⭐⭐⭐⭐ 







  
  
    Perfect replacement
  

*by A***R on Reviewed in the United States on 13 January 2024*

I used it on my boat to replace the water level rod.  I ordered the same size, works great with existing meter.

### ⭐ 







  
  
    Worked once
  

*by J***E on Reviewed in the United States on 27 August 2024*

I had a new under deck fuel tank installed in my  boat. Worked good for 1 outing, then stopped working. The whole floor would have to be replaced in order to put a new one in !
