The fuel system includes such components as a fuel tank, lines, in-tank high pressure fuel pump, PGM-FI main relay, filter, pressure regulator, injectors, and fuel pulsation dampener. This style fuel injection system delivers pressurized fuel to the injectors with the engine ON and cuts that fuel delivery when the engine is turned OFF .
Acura prides itself in being a technologically advanced automobile manufacturer. This is seen in various aspects of the company's design philosophy, and the fuel injection system was not an area to be left out. For example, on the Integra GS-R models, the fuel injectors were altered by a mere eight degrees from their previous design. This was done to position the injectors directly at the center of the intake valves to further enhance the vaporization of the sprayed fuel with the incoming air. This reduced fuel condensation on the intake walls and improved driveability as well as throttle response. As you can see, the fuel injection system was carefully designed and tested. Therefore use caution and common sense when disconnecting and reinstalling fuel system components. Precision and accuracy count!
