im replacing my fuel filter now and it's soooo hard to get to the damn thing. Do i need to drop the differential? How easy is it to drop it? Has anyone every replaced it before???? I need some feedback please!!!!!

Search, there's a huge detailed thread about this that was fairly recent (Maybe 1-2 weeks ago).
Unless you are getting yours gas from an old rusty cell on an old farm ou don't need to change it. I know many will disagree though.
thanks...but the fuel lines on the FIlter are SUPER tight and i can't get them unscrewed. It's soo aqwared, However you spell that. the bolts are so tight, it's a pain.....still haven't gotten anywhere and it's been 5 1/2 hours.....JUST TO REPLACE A FUEL FILTER!
yeah, its a pain, ist ahrd to get to, but you dont have to drop the diff or the tank
just disconnect the fuel line comin from the tank, then take the line off the fitler when you get it out

will all my gas come out?? I've got 1/4 of a tank full. But first of all. What are the side effects of having a bad Fuel filter?? just to confirm My problems.
I was gonna change my fuel filter cuz i wanted to. But after stripping the nut on the out side of the filter, I was like fuq it, and juss left it. I was able to get the bolt off but not the nut.
well, i didn't strip the bolt yet but it's just on there really F*ing tight. So i wasn't able to get anything done in the 6 hours we've worked on it.

Replacing the Mk-III Fuel Filter
All Mk-III Supras have an inline fuel filter mouted to the chassis just forward of the fuel tank. This is typically overlooked in routine servicing, and especially with Japanese imports, may never have been changed. See the picture below for a view of the innards of a used filter. The innards are just a spiral of tightly wrapped paper, and consequently get progressively more clogged over time.
General run down on how to change the filter:
The Toyota replacement filter part number is 23300-49155. Current (Nov 01) retail price is $62+GST.
*Depressurise the fuel system before starting*. Petrol in the eye HURTS. I can vouch for this… oops.
The filter is attached to the chassis above the diff, and forward of the rail which runs across the car in front of the petrol tank. You don't need to drop the petrol tank to get at the filter, but access may be difficult if you don't.
The filter is attached to the rail with two 10mm bolts - when undoing the filter leave these bolts attached and undo the fuel lines first. On one side of the filter there is a 17mm banjo bolt and on the other there is a 14mm flare nut. These are a little difficult to get off, and I suspect it would be best to soak them in CRC or similar for a while first. The best approach I found was that there is a 19mm boss on the fitting on each side of the filter - a 19mm spanner attached to this gives you something to push against while you try to undo the nut/banjo (the filter mount isn't strong enough for this, and just bends). Undo both fittings, then the two mounting bolts and remove the filter.
To replace the filter, attach the two feed lines before trying to mount the filter to the chassis - it's nearly impossible the other way around. The filter comes with two new copper gaskets for the banjo bolt - make sure you use them. Once it's all plumbed back up you can repressurise the fuel system before starting the car to ensure no leaks. To do this jumper the FP and B+ jumpers in the diagnostic block next to the battery in your engine bay. Turn the ignition on (don't start the car) and you should be able to hear the fuel pump running. Check for leaks for a couple of minutes.

Then your car can look like thisflubyux2 said:use a torch to heat up the fuel line connections to break them loose
the fuel filters that toyota used were designed to never need replacement. ever. thats why its such a PITA to change cause toyota was trying to discourage people who have a fuel filter changing fetish. theres a FAQ about this somewhere, i think on SM.
the only reasons to change it are if you need a higher flow rate (i dont know what the stocker is rated for so i dont know how common that is) or if there was forign matterial dumped in your tank (or if rust is flaking off on the inside).
as for symptoms, i had a fuel filter in my subaru get clogged up once. it was alot like hitting fuel cut but more gentle like. it would drive fine until i had to go up a hill or floored it then it would jerk and sputter and loose power till i was going about 10mph then it kind of came back usually.

yep, that's exactly what my car is doing. I thinks its a mix of dirty old Bosch Platinums and a clogged "never replaced" fuel filter. A full tank will last me 3-4 days with no Gettin' on it.

heres the link to the fuel filter faq.

My injectors were found to be clogged. So, I pumped the gas out of the tank by jumpering FP & B+ & running a hose from the rail into a clean jug. I found particulate crap resting on the bottom of the jug.screaminglemon said:
Although I don't dispute the miraculous capabilities mentioned in your link, my real world experience revealed a situation where filter replacement was advisable.
YMMV.
