    Solid, drop in replacement
  

*by J***D on Reviewed in the United States on December 14, 2019*

Replaced the arm type sender in my boat that was sending sloshing readings in an unbaffled tank.  This was a drop in replacement that fit perfectly in the opening including all the screw holes.  Hardware was solid, hookup easy and works great.

    Our Rinker 192 has a gas gauge that works again!!!
  

*by M***T on Reviewed in the United States on August 21, 2019*

Once I figured out how to remove the backseat (tilt forward anyhow)...  Installation was pretty easy.Removed the 5 bolts and marked the location of the old unit.Lined up the gasket (Holes only line up one way) - There is a small notch in the gasket that lines up with where the wire is coming out (all the holes lined up...).Connected black to black and blue to the pink wire.  Turned on the key and the gas gauge worked again!Some users said they needed to wire it backwards, so before crimping down the wires I tested the functionality first.Very happy with this product, it appears/feels like it should last a long time.  I'll update if anything changes.
