Sending unit read 155 ohms. I decided to take it out of the tank and see if something was hung up. I recall a while back someone had the same problem. After hooking up a meter and moving the arm back and forth a couple of times I realized that the sender was toast. Intermittent open and erratic readings.

Off to the dealer I go for a new sender. He tells me 6 different senders where made and only 2 are available. In Japan. 1 month wait.
Now perhaps this guy isnt on the ball. Perhaps he was looking at the wrong thing.

SO.......I;m looking for a part # or a source to buy a new sender.
