Best way to stop a gas tank leak?
I have a 91 5.0 with dual tanks. The front tank doesn't work and has a leak but is never used so i don't care about it. The rear tank just developed a leak at the bottom right above the spare tire on the passenger side. It appears to have a rusty spot right where the leak is so i assume it's a small hole or crack. What is the best way to combat this leak, is there a good caulk or plastic sealant i can use? I wouldn't know what to look for here, but i need it soon, my ranger is in the shop with a FUBAR tranny, and i need a secondary vehicle that somewhat works. I would have posted under the other gas leak thread, but i don't like to thread jack. Any help is greatly appreciated.
