Re: 92 High Fuel Pressure/Stinks/Runs Rough

Also use a air hose and blow out the return line just to make sure it not plugging up . The fuel pressure regulator has a spring loaded needle and seat with a vacuum diaphragm that pulls on the needle so when vacuum is applied it pulls on the spring and lowers the fuel pressure .
