Procedure:
-first start by locating the filter which can be found in various locations such as under the hood, inside a fender well, by the fuel tank, under the floor, in a frame rail, etc
-determine if the vehicle needs to be elevated off the ground or not

-do this by pulling the fuse for the fuel pump, then start the engine which will only run for a couple seconds until the pressurized fuel has been used up
