Replaced original fuel filter on my 2001. After several trys I still cannot make the forward connection leak free. Lines / flanges are centered in the fittings. Flanges at end of line(s) do not appear distorted/bent at all. Using a new Genuine Toyota filter. As far as I know it's just a compression flange fit with no rubber or metal O ring involved correct ? Filter did not come with any. None found in parts look up. The reason I ask is the flanged ends of the lines appear to have a thin rubber coating. Found a few very thin bits in the bowl I used to catch the dripping gas. I have never heard of using anything in the threads of the fittings except maybe anti - seize goop. Maybe the threaded female fittings on the hard lines have an internal O ring ? I've read the Tech-Write up for Filter R&R. WTF am I missing ?
Thx

I'm not really sure how yours is compared to mine, but mine had copper O rings. Are you sure yours did not have anything like that?

you need to place two washers on each line fitting, one before and one after the fitting going into the filter...then torque it good.

Not sure I follow. Are you talking about each side of the flanged end of line ? Anyway I'm fairly sure now that mine is just a compression fit. No O ings/washers. I'm going to try again with a cheater pipe extension on my flare wrench for more leverage / torque. The bits I'm finding are not rubber. They are thin shreads from a dark protective sealer coat on the lines.

hard to see what you have with no pics...did you get any metal o-rings with the new filter unit??

Torque is not the answer.

These lines are recommended to use a flare-nut style wrench so I can't imagine that an ape is required to set the proper amount of torque so-to-speak.

If you're saying that you have no O-rings or washers and others are mentioning the necessity of them, shouldn't you be looking into some O-rings or washers?

Or have you fixed it and left this thread open.....

Update:

2001 = cpmpression fit. Uses no washers or rubber O rings. I think the same holds true for Tundra and maybe others.
I took it to a shop with a lift. Small bits of that line coating I mentioned were causing my problem. Also easier to torque/crank the fittings not laying on your back.

i just changed mine on my 03 taco, and it's fine. no leaks, hopefully you didn't cross thread the fitting.

yes no washers or anything needed for that filter. They are however quite finicky on the seal obviously. When i did mine it was leaking due to a little rust that was on the threads that were exposed originally. a little nudge and all good.

Try some teflon tape on the threads of the fitting. Yours must be mishapen somehow and not maintaining a good seal.

On 96-02 3.4L they are flare fittings (and actually they are flare on 2nd gen 3.0L as well).
The banjo fitting fuel filters are usually used on the 4cyl motors.

Here's a good writeup for 3rd gens:

Glad you got it licked and sometimes it's hard to see if the threads get gunked up.
