Understanding the gas tank capacity is necessary. Trying to drive with nearly no gasoline, the tank will definitely be damaged terribly. But little did drivers know, the gas crust will also be used to provide energy instead of being left in the filter. If a car runs out of fuel regularly, the crust will stick onto the fuel tank, engine, other car parts and slowly corrode them.

Since energy tanks are made of metal, it attracts and collects the gas crust, which leads to corrosive phenomenon and damages the vehicle. This is a serious problem and happens to many old cars.

The Fuel pump, which sits in your fuel tank and pumps gas to the engine, so your car moves when you press the gas pedal.

However, driving with an empty fuel tank will have a direct impact on not only the injection but also the filter system, since the crust inside the fuel tank will also be collected in the injection. And the damaged fuel pump or fuel injector might not display symptoms right away. 

As a matter of fact, the gas crust will stick inside the filter. Later, even after being pumped, the gasoline was still unable to reach the burning tank. Drivers will not start their cars in this situation.

After refilling the gas tank, try turning the key to On mode, then back to Off mode a few times to prime the fuel pumps. Priming the fuel pump will help remove air that may have entered the fuel lines as a result of running out of gas. But what if priming the fuel pump doesn’t help to start the vehicle? It is what happens when car run out of gas and the injection may clog. At that time, you should invest in a fuel system inspection and cleaning. Taking your car to the garage, repairmen can clean out fuel injectors and restore power to your engine. If you left the injectors in that situation for too long, you may have to replace it.
