More than likely, there are two separate issues with those gauges. The fuel gauge may have a faulty sending unit inside the tank. The oil pressure may have a faulty sending unit on the block. iwould be way more concerned with oil pressure, and replace the sending unit to see if that solves your problem.Better yet would be to add a mechanical oil pressure gauge for a more accurate reading, since the "NORMAL" gauge doesn't show you the actual psi, JSM84

You may also check your grounds, the little ones on each side of the radiator support and the one inside the cab on the drives side just under the dash on the metal lip at about your knee height.
