I noticed something hanging down from the bottom of the vehicle and on inspection determined it to be a fuel tank support strap. I took the vehicle to my mechanic for further inspection and when he put the vehicle on a lift one of the two support straps had corroded completely in two and the other strap was ly corroded nearly as bad. If the second strap had also broken and allowed the fuel tank to drop and drag on the pavement there could have been a severe fire. I had my mechanic replace both straps immediately today 11-2-16.
