Fuel Delivery

Fuel Delivery

Fuel delivery starts in the fuel tank.  When we pump gas into our cars, the gas goes straight to the tank where it sits until the car is started.  When the key is turned, a fuel pump draws it out of the tank and into fuel lines to fuel filters that separate contaminants from the gas and it then travels to the fuel injectors (modern cars) or to the carburetor (older cars).  The fuel injectors then atomize the fuel.  From here, there are a couple different ways the fuel is delivered to the combustion chamber.  In a "return" type system, a fuel pressure regulator determines the amount of fuel to delivered depending on the intake system vacuum.  In a "returnless" type system, a PCM (powertrain control module) controls the amount of fuel delivered. 

The quality and type of components used in a fuel delivery system dictate horsepower and efficiency.  Zero In Racing has high performance fuel delivery components such as fuel filters, fuel  heaters, FICMs, fuel injector sets, fuel pressure regulators, fuel rails, fuel pumps and more!
