1. Fuel Gauge: First, check the fuel gauge itself to make sure it's working properly. Turn the ignition key to the "on" position without starting the engine. The fuel gauge should indicate the correct fuel level. If the fuel gauge is not working properly, it may be providing incorrect information about the amount of fuel in the tank.
2. Fuel Sending Unit: The fuel sending unit is located inside the fuel tank and is responsible for sending the fuel level information to the fuel gauge. If the fuel sending unit is faulty, it may be sending incorrect signals to the fuel gauge, causing it to indicate that the tank is empty when there is still fuel remaining.
3. Fuel Tank: Check the fuel tank for any leaks or damage. A leak in the fuel tank can cause the fuel to escape, leading to a decrease in fuel level and potentially causing the vehicle to run out of gas prematurely.
4. Fuel Pump: In some cases, a faulty fuel pump can also cause the vehicle to run out of gas at a quarter tank. A weak fuel pump may not be able to deliver sufficient fuel to the engine, resulting in the engine stalling or running out of gas even when there is fuel in the tank.
If you suspect that there may be an issue with the fuel gauge, fuel sending unit, fuel tank, or fuel pump, it's best to have the vehicle inspected by a qualified mechanic to properly diagnose and repair the problem.
