Fuel pressure at rail is 42...while at idle. Push on gas easy and no pressure increase.....Push on gas hard and pressure falls to 20....car will lose power and shutter...Replaced fuel pump 5 months ago....pressure would rise when you push on gas pedal...now it falls...If you push hard goes to 20-10lbs and car shutters....could it be the filter? the pump, or bad connector to harness losing volts...Please help.
