Gauges

Someone told me that there is a universal combination fuel gauge and sending unit you can buy. Is there such a thing? I can't find it in Summitt or Jegs. Either the gauge or the sending unit is bad on my '57 Nomad (reads over full when the sending unit wire is disconnected and stays at about 1/4 tank when the sending unit wire is connected to the sending unit). I would think a combination sending unit and gauge would be cheaper than ordering it specifically for my vehicle.

I don't quite understand your question. How would a 'combination' sending unit/gauge work? One part needs to be in the tank and the other part needs to be in view of the driver. The root of your question, I gather, is "do the sending unit and gauge need to be the same brand and matched to each other", to which the answer is definitely. The resistance of the sending unit and gauge must be matched for them to work properly. Assuming you want to keep the stock '57 gauge, you are stuck with having to buy a new sending unit, if it is bad. I doubt either is faulty - the gauge is acting as it should when you connect/disconnect the sender lead. Senders usually don't fail part way. They either have an open circuit and don't work at all or have a bad electrical ground and do what you describe. Are you sure your gas tank is electrically grounded to the chassis? Try running a black ground wire from one of the flange screws on the sending unit to a screw in the frame. Clean under the screws to white metal and use star washers.
