I sent my fuel sending unit in. Just after two days of having it they are done. The top of it was fully rusted, the fuel line broke right off from the top of it and a wire had to be reconnected. So they placed a new line on it. sand blasted the whole unit and fixed what ever wireing needed to be done. Then coating it in zync so it wont rust and testing it to make sure it doesnt leak. It only cost $125 plus shipping.
