I recently just rebuilt the front halve of my motor on my 350 olds I now know that the oil sender unit is working fine. But here's the question when I turn her over the only thing I here is the fan spinning. Have new fuel lines and sending unit in the tank when my dad and I did the tank a few years back. I've replaced the fuel lines and the only thing I don't have on the carb is the kick down for the transmission.
