How do you remove the fuel pressure on the hoses that feed the fuel pump? I need to pull the fuel sending unit and clean it. I have heard you can pull the fuel pump fuse and start the car until it dies. I also heard you can enter a code (OBC) that will disable the fuel pump, then run the car until it dies. Any one know the code? Is there another way? I am guessing the tank is at about 1/2 level and I need to get this done asap.
