Gas Tank leaking
 

I filled up yesterday and noticed my tank is leaking around the filler neck. I bought a new seal for it assuming that it is the problem.

I think I already know the answer to this, but do I have to drop the tank to get the new seal on the filler neck?

It looks like something has leaked closer to the top of the tank. I hope this is not a leak on top and is just some junk that has somehow worked its way up there. Are these tanks known to eventually leak from the top?

Pull the inside panel in the trunk and check it out. When my car was new, the overflow wouldn't drain. I pulled the panel and found the overflow hose was kinked when the car was built. I think the filler tube is accessable there. It's been a long time, so I'm not positive.

Thanks for the tip. I have already dropped the tank and changed the seal though. Hopefully that takes care of my problem.
(I guess I knew the tank would have to come out before I posted, but I was just hoping it wouldn't :D) It just took about an hour, so it was not too bad.
