i installed a mechanical oil pressure gauge in my 83 f100. the stock one just sucked. my gas gauge on my back tank is 1/4 tank off towards full. so when im on 1/4 tank im really on empty. but my front tank gauge worked until the tank rusted through and i took it off. i need a mechanical temp gauge but ran out of room to mount it. my oil pressure gauge is under the dash to the left of the ashtray. theres a constant voltage regulator behind the instrument cluster that supplies 5 volts to the gauge sensor. you might try changing that and the fuel tank sending unit. that would probably fix the gas gauge. then buy a guage set for the oil pressure and temp. you can buy a gauge pod for the a pillar so you can mount gauges there. i need one for my truck. they sell em in jc whitney.

Your truck has an "instrument cluster voltage regulator" on the back of the cluster. It is about an inch and a quarter long by half inch square. It has a mounting tab and plugs in to the cluster with terminals like on a 9 volt battery. When they go bad the gauges will act really weird. Hope this helps.
