Where is the fuel filter located on a 2000 Ford Mustang 3.8L v6?

Also do you relieve fuel line pressure by pressing the fuel pump shut off switch and then running the engine until it stalls out?

It is probably under the drivers door
right rear by the tank
actually on the car body basically right above the rear end (actually it’s a little behind that) but requires the fuel pressure releaved at the schrader valve up front (looks like a valve cap on the piece…depress to releave pressure) and jack up/ jack stand the vehicle for access
The fuel pump shut off switch is an inertia switch that shuts off the fuel pump if something strikes the car such as in an accident (although a light tree branch falling on it will also do it). Pressing that switch resets the switch to turn the pump on when the key is turned on.
The wire harness connector should be disconnected from the switch and the key should be cycled to “ON” several times. This should relieve the pressure, which in the Ford EFI system is a constant 39PSI (Even when the car isn’t running, the pressure stays up in the system)! You could also start the car, but turn off the key as soon as it stalls from lack of gas.
Use eye protection as in goggles just in case! Follow proper procedure to jack up and secure (jackstand, etc.) the right (passenger side) rear of your car. You’ll normally find the fuel filter as a can -looking thing mounted just in front of the fuel tank. You may have a metal shield in front of it whic needs to be taken off. There should be two white hairpin clips on either side of the filter, which need to be removed with long-nose pliers at which point the lines can be pulled directly out of the sides of the filter. Remember, the filter is still filled with gas, so don’t tip or… Replace with a new filter with the arrow pointing in the direction of fuel flow (pointing at the line going towards the engine). Make sure the rubber lines seat FULLY on the metal ends coming out of the filter. Do not re-use the old clips – if you buy the filter from a chain store or from your local WalMart (usu. $10- 20) you should get a new pair in the bubble pack – use them, making sure they hold the rubber line secure past the bulge in the metal end of the filter so it’s properly secured. Replace the shield if there was one, then bring the car down.
Re-connect the wiring harness to the fuel pump inertia shut off switch, then press the button. Have someone look under the car (using eye protection) while you cycle the key to “ON’ (not to start) for about 5 seconds, then back to “OFF”, then repeat to “ON” for another 5 seconds, then “OFF”. If your friend sees any fuel spray or leakage, then you must not have secured the lines to the filter properly and you need to recheck your work!
If there’s no leaks or spray, then go ahead and start the car, it may take a moment or two to turn over. If it doesn’t, try again. If nothing still happens, then you may not have reconnected the harness to the fuel pump shut off properly or you need to depress the switch.
Good luck and enjoy your “Stang:-)
P.S. A good manual (Chilton or Haynes) goes a long way!
