Delamination of the diesel fuel tank can occur resulting in a loss of power due to debris clogging the fuel filters. In some cases the fuel injection pump and/or fuel injectors have also been damaged. Ford has issued a service bulletin (#19728) addressing this concern. This issue can affect all diesel F-350, F-450, F-550, F-650, and F-750 Super Duty models.

1999 Ford F-350 Super Duty Problems
A severe lack of power may develop because the hose from the turbocharger to the intake manifold can come loose, resulting in loss of boost pressure to the engine.
An illuminated Check Engine Light could indicate that one or more of the ignition coils has failed due to excessive spark plug gap. To fix this problem, the ignition coils that have failed, the spark plugs, and all coil boots should be replaced.
There is a technical service bulletin for the V8 engines regarding a possible problem with the spark plug being ejected from the cylinder head, damaging the threads in the spark plug hole. If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.
Using the correct oil for this engine is critical. Improper engine oil can foam in the high pressure system and not develop enough pressure
for operation. Symptoms of this can be hard starting, long cranking
time before start, rough engine idle, and a lack of power. Another sign
is tiny bubbles in the oil on the engine oil dipstick after the engine
is shut off. The additives in the correct oil that protect against
foaming can still break ...

1999 Ford F-350 Super Duty Reviews
my truck is 13 years old that 7.3 L still going strong runs great and looks . looks like new.no big problems
I purchased this truck new in Sep/1999. It now has over 185,00 miles. The 7.3 Turbo Diesel is the best engine ever. It still looks as good as new, and there are no squeaks or rattles. I have never had any maintenance issues with this truck in any way until last week, when the transmission finally went while towing my boat back from Lake Havasu.
It did not strand me. It did overheat, but I was still able to limp home. Tranny temp is very critical on this model and is the only enemy that can destroy one fast. When I first had the truck serviced back in 1999, there was a recall for the flex plate that Ford replaced. We discovered that it was cracked again last week when we rebuilt the transmission, and had to replace it on my dime this time. The flex plate cost about $300.00 alone. Other than that, this has been the best truck I have ever owned. I just sold my 2002 Chevy 1-ton with the Dura-Max and Allison. The 5- speed auto was nice, but this truck could just not keep up with the Super Duty! I am in construction and use it daily, hard, and tow often too. My only regret is that I did not buy two back then, so that I would have a spare to replace that 1-ton Chevy I experimented with for a couple years.
