Either the fuel tank sender in the tank is bad and needs replacement, or the fuel gauge is faulty. I would bet the one in the tank is probably bad, because that's usually the case. Find the connection at the fuel tank, disconnect it and use a VOM to get a resistance reading while the tank is empty and reading 1/2. It should match the specs.

The tension pulley is nothing but an idler wheel that puts tension on the belt to prevent it from slipping. The bearings in the wheel dry out or the wheel cracks. If you look you will see it. The serpentine belt wraps around it. It is not a pulley that is attached to any component. You will have to use a tension er bar or ratchet with a long handle to push down on it you will see that the bracket it is attached to will pivot when you put on the pressure. A bolt goes through the center of the pulley. You will have to remove the bolt to get the pulley off. Some are reverse threaded so be careful. Replace it with the right size pulley. If the pulley is plastic, see if you can get a metal one of comparable size. (NAPA parts are ood replacements) Reverse the removal directions and reinstall belt.

There are dyes you can put in with the refrigerant to detect where your leak is.
