    I have an 88 blazer that I just got done restoring and use it as a DD. The fuel guage only reads down to a half correctly, after that it just stays at a half. Can anyone help me with this? I replaced the sending unit and gauge but no difference. One thing though, when I looked at the wiring diagram I see that there is only 2 wires coming from the sending unit. It was like this on my old sending unit, but the new one had a 3 wire harness?
