100Tech20"(510mm) Marine Fuel Sending Unit Float Replacement for Boat Vehicle RV Fuel Sender Gas Tank Sending Unit Diesel Level Sending Unit Water Level Sensor Fuel Gauge Sending Unit 240-33 ohm

Easy to install if you have access to your fuel sensor. Mine are under my seats through an access panel. It’s was a pain getting to the bolts. But this was no fault of this product. But the bolts that came with this were to big and did not fit the threads. So I simply used the old bolts. All good. Gas reading on gauge went up to about half when before I was reading empty or maybe 1/8 of tank. So this definitely seems to be the fix. FYI, read the directions this has the 5 hole design and it only fits one way. Just turn the sensor until the holes line up

The boat sending unit looks good and appears solid.On my gauge, it read backwards. With the float in the full position, the gauge read near empty. As the float dropped (as I was testing it) the fuel gauge rose.My only criticism is the lack of nuts for the screws. You either have to supply your own, or the tank has to be thick enough to tap the tank.I missed the return window as I was gathering parts for an overhaul, only to find that it wouldn’t work for me.As a bit of caution, make sure you know the resistance range (empty to full) required by your gauge set.

Good quality, easy to install and accurate.
