Will Flushing Fuel System Solve Car Shaking Issues?

Flushing out the fuel system in a car can stop shaking caused by contaminates or water in the tank or clogged vacuum hoses. Older cars often have crud at the bottom of the tank that can suck into the fuel system when the fuel level is low. A real fuel system flush can clean out the tank and any crud in the system.

Fuel contamination

Water and sugar can get into the fuel system and contaminate the fuel in your car. This can happen when the fuel level is low and the contaminate/water sinks to the bottom of the tank. A real fuel system flush can clean out the tank and any crud in the system.

Every car has vacuum hoses that connect to different parts of your engine and help to clear the by-products of gas – exhaust fumes. A hose that is leaking or broken can cause huge amounts of shaking in your engine. If your hoses are disconnected or worn out, many other engine problems can begin to occur.

If your car has a valve, it may be experiencing an EVAP purge issue if it has been overfilled with fuel.
