Early on Frank posted that the fuel senders tend to go bad and since I don't have power to the boat yet I pulled the sender and tried to check it.



The resistance did not change, am I doing something wrong? I assumed there would be a slide in that tube so I pulled it apart but did not see any slide. Does the resistance change as the fuel moves up and down on the tube?

I see there's adjustments on top of the sender but I didn't touch them:

Thanks, Steve
The highest that sender should read is 240 ohms give or take a few ohms. Fuel Sender 101 thread will help. I am sure you will need a new sending unit.
