most are in the gas tank.
Easy job if you have a floor jack, 2 floor stands and wrench.
Empty the gas tank, place jack centered on the gas tank jack up the car, put the floor stands in place to hold the car steady, disconnect the wiring go to the gas tank then remove the bolts (most cars only have 2 holding the tank braces, slowly lower the floor jack with the tank on it, remove the fuel pump slowly and carefully as not to have anything fall in the tank.
