Review on Spectra Premium FG156A Fuel Sending by Eric Power

I bought this because I changed the fuel pump - so I might as well replace it while I have everything disassembled and everything in the tank is new. There was nothing wrong with the original old unit that came from the factory - it read correctly - but this new one only reads 3/4 of a tank when the tank is full. I recommend sticking with the original GM station, which I believe is AC Delco.
