1989 Mercury Sable 3.8 wagon

My car is having a problem where the fuel gauge doesn't read correctly. I have just tried to fix it by dropping the fuel tank and replacing the sending unit and pump. It is still reading wrong, so now I am wondering what other things can cause this to happen. I am thinking about replacing the instrument cluster because that is the only other thing I can think of, all the other gauges are working and are accurate. Also is there any way to possibly repair the cluster I have, if it is the problem?

Another thing I have been trying to figure out, if I replace the cluster with a picknpull one how do I change the odometer to match

It's possibly the anti-slosh module. It's located on the instrument panel board. If you get a replacement dash, you could just replace the speedo from the one you take out. Check all of the connection on the board. That may fix the problem.

I definitely will. I will most likely need to wait until about thursday or so in case the car is out for a couple days

So I have gotten the fuel gauge to work again by switching out the instrument cluster... now there's a new issue though... the speedometer does not work at all.
