Wire a fuel gauge by first disconnecting the old dysfunctional unit to replace it with a new one. Obtain 12-volt power from the fuse box using a standard wire, and connect it to the positive terminal of the fuel gauge. Next, connect a wire from the float on the fuel tank to the negative terminal of the fuel gauge.Know More
When wiring a fuel gauge, it is wise to have a full tank in order to monitor the installation correctly. Next, gather all the necessary tools and equipment together. Be careful not to use power tools around the fuel tank, as it can lead to combustion or explosion.
The float is usually made of fiberglass and connected to a resistor. If wired wrongly, there will be some inaccuracies on the fuel gauge reading as compared to the actual volume of fuel in the car’s tank. For example, the needle on the gauge may remain in the "full" position even after travelling a considerably long distance. On the other hand, the needle may remain on the "empty" position even after the car has been fueled with a considerable volume. The shape of the fuel tank can also cause these errors, as they may be shapelessly designed to fit in the frame of the car.Learn More

Flex-fuel technology refers to a type of vehicle that has an internal combustion engine that can run on either gasoline or up to E85 gasoline-ethanol blend. A sensor in the fuel system measures the ethanol content in the fuel, allowing the engine's control unit to adjust the engine's tune accordingly.Full Answer >
The lifespan of a fuel pump is typically 10 years, although the wear and tear on the vehicle over time can increase or decrease the lifespan of the vehicle part as well as the effectiveness of the fuel pump. Many fuel pumps come with a standard one-year warranty guarantee and customers often have the option to expand the warranty for a fee.Full Answer >
An oil pressure gauge can fluctuate for many reasons, including an actual automotive problem as well as reasons like fluctuation in oil temperatures. In most cases, the gauge will fluctuate to indicate low oil pressure. When the gauge fluctuates to indicate high oil pressure, it is often indicative of a pressure relief valve problem.Full Answer >
