I just found out that my fuel tank is leaking (well, more like seeping). I've been smelling a fuel odor near the drivers rear tire, so I crawled underneath and found an oily spot on the edge of the tank at a seam. It's a bit rusty too. I wiped it with my finger, smelled it, and yep it smells like feul. Is this repairable? Or am I looking at a new tank. I looked it up, and a new tank is $245, which isnt that bad, but it looks like an absolute pain in the ass to replace. What should I do?
