Hi, I was checking my fuel system and fould that when I bled the fuel lines, there was practically no pressure to be relieved.. Also, the return line to the fuel pump had no fuel coming in to it. Is that the way it usually is? The filter seems to be clean. I did this after I had driven the car and let it stand for an hour or so. The car is a 99 accord 4 cylinder. F23A1 I have been having acceleration hesitation, power loss and mileage loss and hence the checking. Thanks, es
