The description and function of the Evaporative Control System is located in Emission Control Systems. c) The outlet port is located at the bottom of the fuel pressure regulator. So whatever you set your adjustable fuel pressure regulator at you will have that same differential pressure in any vacuum or boost. Study with Quizlet and memorize flashcards containing terms like Technician A says that the fuel pump relay is usually controlled by the PCM. The major difference between the two systems, besides the absence of a return line with returnless-type systems, is the location of the fuel pressure regulator. However, the FPR has a return line to the tank, so excess fuel is returned. this the SCT settings return system Returnless Fuel Pump -> Fuel pump voltage table - set all the cells to max value, usually 15 volts.
