Fuel Filter Change

Hey everyone, I have a 2000 mustang gt and I need to change the fuel filter. In the past, it has just been done by my mechanic, but I want to do it myself this time. I was wondering if anyone had any instructions they could give me on how to go about changing it. To be honest, I don't really know where to begin, so all help would be appreciated. Thanks much

To start, the filter is over the rear axle.

1. Bleed the fuel pressure at the fuel rail
2. Disconnect the battery
3. Pull the hoses from the filter
4. loosen the filter from its base
5. remove

easy done in 10 mins.
Wear safety glasses, some fuel will spill from the filter.

releasing fuel pressure

Sorry, could you explain "Bleed the fuel pressure at the fuel rail"?
I dont want gas spurting all over so I know I have to do this, but not sure how.

I wrote this up a while back on another site, but you can pretty much get the same directions on BULLITT Archive Home Page

Tools/equipment needed
1. Motorcraft Fuel Filter--Part #FG-986B
2. 5/16Fuel Line-A/C Line Disconnect Tool. (Any autoparts store has them)
3. Flat head screw driver.


1. I first backed the car up onto my Rhino Ramps.

2. Disconnect the fuel inertia switch that is located in the trunk. This switch cuts off fuel

3. Next find the Schrader valve that is located by the throttle body, which is located at the end of the fuel rail towards the front of the car. It looks like a tire valve.

4. Once the Schrader valve is located unscrew the cap of the Schrader valve and use a small screwdriver or something to release the fuel pressure. This is much like letting air out of a tire....just press down and it will release the pressure. I would recommend wrapping a shop rag or towell around the Schrader valve and whatever you use to release the pressure. Gas will shoot up, not a lot, but enough.

5. Once you have the inertia switch unplugged and fuel pressure relieved start the car and let it idle until there is no more fuel getting to through the lines, which will cause the car to die on it's own and should minimize the amount of fuel that is released when changing the filter.

6. Next unplug the battery. I didn't do this, but my car threw a code after unplugging the inertia switch and used my predator to clear it. I think unplugging the battery will reset the computer after plugging the inertia switch back in when finished.

7. Get under the car and locate the fuel filter, which is right behind the gas tank.

8. Unscrew and remove the clamp.

9. Pry the fuel filter out of the the housing, which will give you a little room to work with.

10. Then take the 5/16 fuel line disconnect tool and slide in on the fuel line and move it to the outside (away from the fuel filter).

11. Once you get the fuel line disconnect tool slid all the way in, then pull the fuel line off the filter. A little bit of gas will come out so have something on the ground to soak it up.....I used some cardboard that I had left over from moving. I would also suggest goggles so fuel can't get into your eyes. Not a lot of fuel came out when I did this, but you never know.

12. Re-connect the fuel lines to the filter, but make sure the arrow on the filter is pointing toward the engine side of the fuel line.

13. Slide the filter back into the housing and put the clamp around the filter.

14. Re-connect the inertia switch

15. Re-connect the battery

16. Make sure to put the Schrader cap back on.

17. Put the key in the ignition and turn it to the on position and leave it for a few second, but do not start the car. Do that a few time to allow fuel pressure to build back up.

18. Check for any leaks.

19. Start the car and your done

Be thankful you don't have an IRS. That makes it a PITA to get to. I unplugged the inertia switch and let the car stall. I think it's the easiest way to bleed the fuel lines.

I always just put vise grips on either side of the fuel filter, as soon as I pull the hose. There are some made with rubber inserts so it doesn't cut the fuel line. Been doing it this way since 97.
