*NOTE* YOU SHOULD DO THIS WITH THE WHEEL OFF, IT IS IMPOSSIBLE WITH IT ON!

Ok, so when I got my 4runner, I didn't notice anything out of place until I got it home. Smelled like gas. Nothing unbearable, but there was definitely something wrong with it. Took it to the local Toyota expert, who said it might be the filler neck. Took off the cover for it, and the pipe was pretty corroded, but not rotted through yet. I decided to replace it before it got to bad, which was definitely a good idea by how much of a pain it was before it was even rotted!

So, there are 4 clips holding the cover for the neck in place, they look like this.



This is a picture of the cover itself, there are 2 clips at the bottom, 2 at the top. You can just pull them off with a pry bar, or a flathead screwdriver.



Once I had the cover popped off, this is what I saw underneath



You can see that there is a bolt there holding it on. If I had a way to show you the rest of what you need to remove, I would. I could not get the camera anywhere I needed it, so I'll explain as best I can. You have to remove that first bolt, there is a second bolt at the frontmost curve holding the neck to the frame. We happened to snap ours off. If that happens to you, there are holes next to it that you can use, we used a 5/16 cutting bolt (I'm pretty sure), since 7mm and 8x 1.25 shank bolts wouldn't work in the hole we chose. There is a hose clamp holding the neck itself into the rubber boot which connects to the tank. If yours is rusted, just break it off, it isn't worth it. There is also a spring clamp holding on the breather, I just used a smaller pair of needlenose vise grips to remove that, MUCH easier than pliers! After that, all you have to do is remove the gas cap and pull the neck through the rubber grommet thing that holds it in place. Wiggle it around until it comes free, then pull the neck out through the fender. Feed the neck back in the same way, and put the top end into the grommet first, the rest of the operation doesn't matter as long as the filler neck and breather are in and tightened. Here's a picture of the hose clamp and spring clamp:




Here's the difference in the old and the new necks:





And finally, the new neck in place as viewed from the fender.



Hope this helped anyone that views this thread! I am not sure if the necks are mounted the same for all 4runners, but it should be for all 3rd gens (mine is a '98).

Nice, I'm sure it will help someone!

Thanks, I was hoping for a reply, I was feeling like I wrote that for no reason. I know for sure I'm doing the build thread for no reason lol, it's all small things, not lifts or engine swaps haha.

thanks, man. it's exactly what I needed.

Nice job!!

Gotta love New England winters with their salt mixture on the roads.
Where in CT are you from??
I live in Torrington

I didn't get a message about your reply, I live in Ellington, pretty close to the Mass. line. Good luck with the storm today!

what is the part number? i smell fuel every time i turn it off. the little flapper thing inside the neck is missing too! that's probably what's causing a P0442 small evap leak code to pop.

Im digging this up because I have done everything all the other threads say to do for this damn P0440 code. I am now going to check my filler neck in hopes that I can fix it without needing to replace my charcoal canister.

So far I have replaced the 02 sensor, the AF sensor (i have a CA model), the gas cap, and I have cleaned the MAF sensor. Car runs great, but throws P0440 about 25 miles after the code gets reset.

So....my question is.....should I be able to SEE if this neck needs to be replaced when I pull the cover off and see it? Am I literally just looking for rust and or holes in the neck?

I'm actually about to do this. I'm going to replace the rubber hose as well. Anyone know if I will have to drop the tank to replace both?

Very sorry to all of you for the extremely late reply. As I'm sure all of you know, life gets in the way sometimes, so I've just been trying to get my situation squared away. When I looked at my fuel filler neck, I figured it would rot through in the winter, so I just replaced it right away. Otherwise you'd have a leak like if you'd left the gas cap off, which usually throws a code. As for replacing the rubber hose, I'm not sure whether or not you'd have to drop the tank, sorry.

I actually got my parts in today to swap it out. The filler neck I have has more lines that what you show. Mine is an 01 though. Hopefully won't take me too long.

I know this is an older thread, but could you tell me where from and what parts you ordered Otis? Thanks!

I got mine from ToyotaPartsCheap.com. Also the 2001 filler neck looks different from what is in this thread. It was a pain in the ass to fit in there. Took two people one under the truck and one up top. You have to put it in from underneath.
