If the sensor is in the fuel rail I have a hard time believing it is low pressure. Your going to have to find something before the HP pump. Just doing a quick google search it sounds like the is a low pressure sensor in the fuel lines coming from the tank just as they get into the engine bay. You could probably "T" it there.
