Fuel System

An electrically driven fuel pump, forces fuel through a filter, into the main system. Located in this system are, one injector for each cylinder, and a pressure regulator that maintains fuel pressure at 28 psi in the main system. A secondary system carries excess fuel from the pressure regulator back to the fuel tank.
