Ford and fuel tanks are a sore point with me. I have had two Ford vehicles drop their fuel tanks on the pavement after the straps rusted through. This isn't exactly a maintenance issue, since the owner can't see the straps, and they are exposed to road salt.
This was about 15 years ago, but I haven't forgotten.
Guess that makes it "Fix Or Repair Droptank???" I think my last Dodge truck had a plastic tank. Don't know that that made me feel good...static....TWA800....hmmmm.
