The two vent lines (which I'm assuming are vent lines) attached to the filler neck are rusted to heck. I'm smelling gas fumes intermittently and I'm assuming that this is the cause. If I get a replacement filler neck, what else do I need, accessories wise, such as bolts, clamps to hold the filler neck? I'm thinking of replacing all that stuff too because I'm assuming that these will be rusted a;so.
Also, can anybody point me to a decent how-to on how to do this? The only thing I'm afraid of are the rusted bolts..I have a feeling that I won't be having a nice day after I start taking all this crap apart. Any tips and tricks on dealing with removing rusted bolts and such would also be appreciated.

Edit: The car is a 98 Corolla.

Before replacing anything, diagnose and verify that is where there is a fuel leak and why you are smelling fuel odors. You could go to a lot of time, trouble and expense to repair something that might not even be the cause of the fuel odors.

To diagnose, use a strong light to look at those fuel lines and the filler neck and see if you can find a fuel leak. A fuel leak is a huge safety issue of course so this is something you want to be absolutely sure is correctly pinpointed and repaired. Otherwise someone walking by your car with a cigarette and tossing it to the ground, igniting gasoline, could cause your car to burn to the ground and if you were inside, that might put a bit of a crimp in your day. :blink::eek::(

Some fuel filler necks are very expensive and you can save some decent money by purchasing a good used, rust free fuel filler neck. The below website can help you locate one -

I figure that even if the smell isn't coming from the vents, I would feel safer by replacing the fuel filler neck just because of how rusted it has become due to all the salt on Canadian roads.
But I appreciate your advice and thanks for the link. I just wanted to make sure what else was involved in securing the neck. I'm assuming a 14mm nut and couple of clamps on the gas tank...but I just wanted to make sure. I suppose I could stop being lazy and take a look underneath.

It should just be a few bolts and clamps. I normally use a torch on rusted fasteners but I wouldn't come near your vehicle with a match lit, let along a torch right next to the filler neck.
