Two problems related to diesel fuel system tank assembly have been reported for the 1999 Ford F-550. The most recently reported issues are listed below.
We have 4 f550 buses that have had the gas tank replaced twice on each bus do what we believe is coating failure. We now have an f450 that is experiencing the same conditions, we are forced to replace the gas tank on this vehicle as well. We take our vehicles to Ford miramar truck center, and have had a Ford factor representative look into the problem only to tell us its not a tank failure issue. After what will now be 9 replaced gas tanks, I truly believe there is an issue here that must be seriously looked into. On a side note, after the second tank failure we changed gas stations thinking the problem was bad fuel-not the problem.
Internal coating failure on fuel tanks on f550 super duty Ford trucks. The fuel system becomes clogged with rust and the tank must be cleaned or replaced. We have four vehicles and have incurred 8 to 10 failures in past three years. We are unable to get Ford to address the problem which I think is improper application of the coating material.
