I am having a problem with my ESOF system. I have checked everything after the solenoid and everything is fine. If I plug the out line on the solenoid I still have the leak. If I plug the incoming line(the red one) I dont' have a leak. I am pretty sure the solenoid is bad. Does anyone know where to find this part online?? Or a way to rebuild it?? Or the part # so I don't have to spend an hour with the parts guy at the dealership trying to explain what I want.
