Just when I thought I had fuel sending units figured out, I come across this in my 2005 Hunter 33-2. Not sure how to test it or what to replace it with.
There are 3 wires coming into the connector from the boat and 6 wires coming from the sending unit.
There are 0 ohms between two of the six wires on the unit and infinite between all other combinations with the unit removed from the tank.
The tank is almost empty. The gauge has always read full since I bought the boat. (I've probably put 3-4 hours on the engine and never put diesel in it.) The gauge reads empty with the wires disconnected.
So I'm pretty sure the sending unit is bad - but what to replace it with and which wires to connect it to?
