Running ethanol in a vehicle that was not designed for it may cause problems with the fuel pump depending on the concentration. This is a good way to destroy your fuel system and potentially the engine. Never put diesel into a gasoline-powered vehicle, or vice versa. Using the incorrect type of fuel is a quick way to cause problems with the fuel pump. Use only well-known and mechanic-recommended fuel system additives. In the same way, be careful of additives for the tank. While any station can have a batch of bad gas, it may be more likely at some than at others.Ĭontaminants or water in the fuel can clog the fuel filter which puts more stress on the fuel pump. Besides choosing the correct octane rating of gasoline, it’s a good idea to select a good gas station for the best chance of having quality fuel. This isn’t an inherent fault of yours or the manufacturer’s most components are built with a specific service life in mind. 1) Age-Related DegradationĮven with the best care, most parts will eventually wear down and break. There usually isn’t a regular maintenance interval, though you can always check the owner’s manual just to be sure. With proper care of the fuel system and good fuel, a fuel pump should last at least 100,000 miles, and sometimes several times that. Newer vehicles with electronic fuel injection have higher pressure needs which can only be supplied by electric pumps. Older vehicles may use a mechanical pump, which uses a plunger or diaphragm to create suction that moves the fuel to the carburetor and then to the injectors. Before the fuel is pushed into the fuel injectors and shot into the cylinders at precise amounts, it goes through a fuel filter to remove any contaminants. The fuel lines won’t be over pressurized as long as the fuel pressure regulator is working. For instance, direct injected vehicles require a secondary high pressure fuel pump to bring fuel pressure from 60-80 psi up to around 2,000 psi or even more. Some vehicles have another pump located along the fuel line or even in the engine bay to further pressurize the fuel. The surrounding fuel cools the fuel pump during operation. The pump is usually located in the fuel tank and submerged in fuel. When you turn on the car, the fuel pump pressurizes the fuel system, which brings fuel toward the front of the vehicle. In most cars, fuel from the gas station is pumped into a gas tank that sits at the rear of the car, even though that fuel is needed in the engine at the front of the car. Other Possible Causes of these SymptomsĪ fuel pump is a simple electromechanical device that transfers fuel from one location to another.
