The moment you put gas in your car, it starts shaking, and you’re left wondering what’s going on. It’s a frustrating experience, especially if you’re in a hurry or have a long drive ahead of you. The good news is that there are several reasons why your car might be shaking when you fill up on gas, and most of them are easy to fix.
What Causes a Car to Shake When Filling Up on Gas?
There are several reasons why your car might be shaking when you fill up on gas. Here are some of the most common causes:
Low Fuel Pressure
One of the most common reasons why cars shake when filling up on gas is low fuel pressure. This can be caused by a variety of factors, including a clogged fuel filter, a faulty fuel pump, or a malfunctioning fuel pressure regulator. When the fuel pressure is low, it can cause the engine to misfire, leading to a shaking or vibrating sensation.
Clogged Fuel Filter
A clogged fuel filter is another common cause of a shaking car when filling up on gas. When the fuel filter becomes clogged, it can restrict the flow of fuel to the engine, causing it to misfire and shake. This is especially common in older cars or those with high mileage.
Faulty Fuel Pump
A faulty fuel pump is another potential cause of a shaking car when filling up on gas. The fuel pump is responsible for pumping fuel from the tank to the engine, and if it becomes faulty, it can cause the engine to misfire and shake. This is often accompanied by other symptoms, such as a lack of power or difficulty starting the engine.
Malfunctioning Fuel Pressure Regulator
The fuel pressure regulator is responsible for regulating the pressure of the fuel in the engine. If it becomes malfunctioning, it can cause the engine to misfire and shake. This is often accompanied by other symptoms, such as a lack of power or difficulty starting the engine.
Worn or Loose Belts
Worn or loose belts can also cause a car to shake when filling up on gas. The belts that connect the engine to the accessories, such as the alternator and water pump, can wear out over time and cause the engine to misfire and shake. This is especially common in older cars or those with high mileage. (See Also: Why Would The Inside Of My Car Smell Like Gas? – Find The Cause)
Bad Spark Plugs
Bad spark plugs can also cause a car to shake when filling up on gas. Spark plugs are responsible for igniting the fuel in the engine, and if they become worn out or fouled, it can cause the engine to misfire and shake. This is often accompanied by other symptoms, such as a rough idle or difficulty starting the engine.
