OK, the how to that I have promised to do.

You will need some tools.
1. 10mm socket
2. At least a 3" extension
3. Ratchet
4. Flat head screw driver/pic
5. 8mm socket
6. New filters, there are two, the housing thing, and the mesh screen
7. Rags
8. Balls of steel, (fuel here)
9. Beer
10. Ventilated area, do not do this in your one car garage
11. Empty or nearly empty tank. (THIS IS THE MOST IMPORTANT PART AFTER BEER)

1. Start off by pulling the rear seat bottom out of the car. This is very easy. On both sides of the seat bottom there are clips holding the seat in. Take a seat in the rear on the pass side, grab the cushioun by your knees and yank up. Do the same on the driver side. Seat bottom comes out no problem.

You will see this on the driver’s side.

Grab a 10mm socket with your ratchet, and unscrew those 3 plastic nuts, lift up the cover.

2. Unplug the harness. Pay attention, push on the tab in front, and pull up. Mine was a little tight, so i gave it a nudge with a screwdriver from the bottom.

3. Harness out, note the yellow clip behind.

4. Push yellow clip toward the pass side, take it out completely.

5. Yellow clip out. Pull the fuel line up, it will come out easy. Get ready for some lovely gasolinage smellage. Sorry for the sideways pic.

6. Same picture as above, look at the perimeter of the circle cup. There are 8, 8mm screws that need to come out. Didn't take a pic of them, but you can see them in other pics. Take them out, if you drop a screw there, look under the car, it will fall through.

7. Pull the entire thing up, don't pull too hard, take off the hose that I am pointing too. You can squeeze that clamp with your fingers. Pull it down. Then pull gently on the pump assembly, and take it out, watch for the level lever.

8. Pump assy out. Peep the nasty looking filter, that is the mesh one, the white plastic thing, the body basically is the other filter.

9. Take apart the assembly. There are 4 tabs on the perimeter, use a pick, or a thin flat head. Note there is one wire harness in there, you can see it without taking anything apart and you can disconnect it with a pic while all is assembled.

10. Notice the harness here. You need to unclip it. Also notice the black tube, that is connected to plastic, that is your regulator, remove it also, it needs a healthy wiggle to get out.

11. Assembly in pieces.

12. ***********MAKE SURE THAT YOU ABSOLUTELLY HAVE ALL THE BLACK WASHER/SEALS OUT OF YOUR OLD PARTS, THE NEW PARTS DO NOT COME WITH REPLACEMENTS. YOU NEED TO MAKE SURE ALL GO INTO THE NEW FILTER ASSEMBLY OR YOUR CAR WILL NOT START. ****************

13. Use a pick to take off the clip here, this will take off the mesh filter from the pump.

14. Put new filter on. Put back the clip (not shown), put back the rubber bushing (shown).

15. Put everything back together, I note once more, that it is absolutely crucial that you replace all the black bushings / washers in their place or your car will not start.

Hope this helps someone.

this will def help. i have to do this. I thnk mine is clogged cuz it takes a couple turns to get my car started sum days. :(

is this the same for a 00' gs400?

yea most likely. The cars didn't really change in this area.

Very nice :thumbup:

Do you have to replace the oring as well, could cause gas leak...?

Which o-ring? The giant one? No i didn't do that. It is very thick, lines back up with the holes, and still has major compression once you bolt everything back down. You'll see once you take it off.

i got question to this filter change when i removed my there ware 2 rubber O rings and two plastic little like O rings also . did anyone know whee they go . i put them back but not sure if i put them in the right places

If your car started, you did it right. If you break, or misplace that O-ring, your car will not start.

thanks for this post

Hmmmmm... Bout to do my 90k service, should i have them change the filter while the car is there. Too scared to do this myself for risk of
1. spilling gas inside car
2. kaboom
3. misplace a seal
4. did i mention number 2

Don't worry, this has to be one of the easiest things I've done with my car. It's very straight forward. You just have to pay attention to where everything goes.

Smelling gas is not a big deal. Just roll down all the windows and open the sunroof before you go to work.

Adding this to my to do list.

If it's too long to read, my advice is to at least follow my tip to to a minimum READ THE SERVICE MANUAL'S STEPS on the procedure rather than relying on a fellow CL's member's writeup and pictures. Every writeup I've seen skips at least one step which may cause you trouble or causes you to guess.
Plus, I don't see the point in re-inventing the wheel when the manual is freely available(for the time being)

The SERVICE MANUAL is in the sticky.

thanks man been thinkin about doing this
