When working on fuel or brake lines you should use flare-nut wrenches. Remove negative cable from battery. Before doing so, know your radio code. Remove fuel filler cap. Slowly loosen service bolt (top bolt) to depressurize the system, while having shop towel/rag around service bolt area to contain any fuel which will exit the service bolt area. Order an OEM fuel filter as some aftermarket ones do not include all 3 washers.
