This is a prime example of exactly what you don't want to see. The DVM is reading OL or Open Lead. This means the sender has had a complete failure and has open-circuited.


Alternative bad readings would be Ω readings outside the 33Ω to 240Ω range. A little over or under is usually okay but too much over or under represents a bad sender.


This is still an El Cheapo type just a different brand. Note the exposed wires, terminals and such inside the tank.
