Changed the fuel filter on the 01'.
110,000 miles, still had the OEM filter on it.

"Mud" was pouring out of it when I cut it in half.

Write up to follow.

Yeah, I have had a replacement filter since last year but havn't been able to put it on. I am expecting to bust my lines taking it off because of rust, so I need to have a back-up ride in place before I do this. Hopefully soon though. With the rust I had on the filler pipe, I am sure that my filter is pretty bad.

Start applying some PB Blaster now. Once it's had time to work a while, wire brush around the exposed threads as best you can. Then more PB.
 
For those who would like a write-up on this, here is one:

*EDIT: I just realized RayRay was going to do a write-up, Sorry for stealing your thunder bro! Check out RayRay's write-up, I've seen some of his other write-ups.....GOOD STUFF!

:D No worries.

Thanks for the kind words. I'm going to get the writeup tonight. I'll link to it here.

Great advice.

Yeah, I have used a couple cans of PB on the vehicle already. It doesn't always work it's magic the way I'd hope though, so I have learned to plan for the worst. It's either have a back-up ride, or just buy the replacement parts.
 
for all of you having "trouble" getting your fuel filter off.....

i tried 4 times with the "right tools" until i said f it and grabbed a pair of vice grips, gloves, and an extra order of elbow grease. clamp them bad boys down as tight as you can (for real, the tightest you can get em) and break her loose. a nice soaking of PB blaster is def a must too. pref no less than 6 hours ahead of time. thats all i had to do. sprayed on at lunch time in work parking lot, went home, cracked it loose.

good luck, it made a HUGE difference. but i think i need another one already because of trash in my tank.


oh, and nelson, i know u got alot of rust action going on. . . but my fuel lines were pretty bad (imo) and it worked. id try the vice grips.worst case senario you cant get it off at all and round off the flare nut. filter will still be there doing what it used to supposed to do. . .

I too am worried about damaging the fuel line wrenching on it so hard. I applied PB the day before, and used the right size wrench. I put a good armload into it, and it wasn't budging. Maybe I'm worried about the line for no reason?
 
Just an advise before pulling the filter pull the fuel pump fuse and run the truck till it dies and they crank it some more to get rid of additional fuel.
 
Make sure you use a 14mm flare nut wrench on the fuel lines, don't want to crush those and cause a leak.

14mm flare nut wrench and an open end 19mm to hold filter body steady.

Put some hot sauce on the rust on the bolts it helps I did this when replacing my fuel filter
 
Would the vice grips eliminate the need for the crow's foot wrench. I don't have such a wrench. I always wondered what they were for. Also, how much gas pours out of the filter/lines if you unscrew the gas cap first? How much did you pay Toyota for the part? I just replaced fluids and did tune up as my '00 has reached 143k. It still seems new to me!

Get a 14mm craftsman wrench (less than ten dollars). Ingenuity, will carry you so far. Having the correct tools for the job is priceless.

Maybe half a qt. of fuel. Pull EFI relay, crank for 5 secs, open fuel cap to relieve pressure.

I think the filter was about 40-50 dollars.
 
while we are on the topic of fuel filters, is there a writeup on how to clean the gas tank? - removal or any debris at the bottom of the tank?
is the fuel pump accessible from inside the vehicle like other small suvs/cars?
 
As per advise on my fuel filter thread I went with a napa gold (wix) for $21. I've used wix oil filters and air filters and it's pretty much the only other brand for filters I use besides OEM.
 
If you mean you are going to use vice grips instead of the proper wrench for the flared fitting then - no. The vice grips can/will bugger up the flared nut and that means a new line. There is a very valid reason that flared wrenches are made and this is one. You can get a cheap set at harbor freight.
