It sounds like you are having float problems. It is not your gauge but the float located in the tank. If you are lucky, and your fuel tank is below the trunk it is easy to fix. Sometime in the 70's or early 80's they moved the tank from below the trunk to the front of the trunk area right behind the rear seat. If it is in the trunk follow these directions. If not locate fuel tank and then look for the sending unit and follow these idirections.

In the trunk, under ther rubber mat, there is a plastic cap about 3" in diameter with a wires going through it. Remove the plastic cap and remove the plug. You are looking at the fuel sending unit in the tank. remove the bolts, be carefull not to drop any because they are difficult to recover. Slowly remove the sending unit becuase there will be fuel in it and you want it to drain out. When you have it out, remove the small nut on the bottom and carefully remove the aluminum tube. Be carefull because the two resistant wires are very fragile and can break easily. Clean out the tube and the retaining cap and plastic washer with all the small grooves in it. If you open it up and there is only one wire left, you need a new unit. If a wire is broken, you need a new unit. Clean out the contacts on the bottom that turn on the reserve light. After you have it all clean, reconnect the wire and manually move the float and see if the gauge works and the reserve light comes on when you bottom it out. If ieverything looks good, put it back together and reconnect erverything.

Good luck

Henry
