![]() ![]() 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.
