One problem related to gas tank strap has been reported for the 1999 Ford Ranger. The most recently reported issues are listed below.
Rear of truck is rotting away to nothing. Had the rear of the frame plated a few years ago where the shackle brackets bolt on. Now I noticed one of the fuel tank straps hanging. The crossmember that holds it is rotted away to nothing. Took the truck to my mechanic. He called me after about an hour & told me the truck was junk. The whole frame & crossmembers from the cab back are rusted horribly. He told me not to even drive the truck because it wasn't safe.
