My fuel pressure is set at 30lbs when the car is not running. When I start the car it read about 60 lbs. is that normal?

If you changed the regulator and the problem still exists, you have a pinched or plugged return line.

If you changed the regulator and the problem still exists, you have a pinched or plugged return line. If a line is pinched or linked, shouldn't the pressure drop ? The pump, "dead-headed" will put out far more than 30 psig. If the suction line is pinched or plugged you will have little or no pressure at all. If the return line is pinched or plugged you will see the total capability of the pumps' output pressure. If you incorrectly hook up the pressure regulator, you will see the same problem ... high pressure in the fuel rails. |
