I know this isn't a Ford but any help would be appreciated.
As the title says I'm looking for some opinions on my fuel system failure. I turned it into my insurance and they are saying it is normal wear and tear. If I could get some replies from some experts on what you think happened and why. Have you ever herd of a entire fuel system going bad all at once. Could this be wear and tear? I don't need names but if you could qualify yourself that would be great.
Here is the scenario

4/1/2011 I got fuel at the Delta Gas Station on Railroad Ave., Patterson around 7-7:30am. Exhibit 01 - Approximately 40-50 miles later, the truck started running poorly and finally got to the point that it needed to be towed.
Exhibit 02 - It was taken to Salerno GMC Dealership, Randolph, they diagnosed the problem, the #5 injector and the fuel pressure sensor were bad.
Exhibit 03 - The truck was then taken too J&J Diesel Repair for the work to be completed. Upon completion of that repair, the truck was still not running right and J&J did not have the computer program to continue working on the truck. Exhibit 04 & 05 -

So the truck was then sent to Gearhart Chevrolet where it was diagnosed as fuel contamination. The tank was dropped and cleaned, cleaned fuel lines, replace fuel filter, start vehicle; runs poorly. #5 and #6 injectors reading +12 out of range, replace #5 and #6 injectors. Start vehicle, still runs poorly, #3 and #7 injectors now reading +12, out of range, replace those. Vehicle ran better but has immediate miss fires, suggested to replace all other injectors. Injectors were programmed each time injectors were replaced. Exhibit 06

Truck still runs poorly, now loosing power going up hills. Replace fuel filter housing and sending unit. Exhibit 07

Truck still runs poorly so replaced and installed new pressure relief valve. Exhibit 08

Truck is still running poorly and loosing power, fuel system unable to reach correct operating pressure, engine fuel pump not putting enough P.S.I. probably related to prior water contaminated fuel, checked system injectors tested good, needs fuel injection pump. Exhibit 09

The Service Manager suggested that I turn this into my insurance due to water contaminated fuel caused all the damage to the system.

Please tell me what you think and why.
Thank you

First off, there is no fuel pressure sensor on these trucks... Not sure where the GMC dealer came up with that.

Secondly, you don't give any information on your particular truck and did not say how many miles are on the truck but fuel pumps do go bad over time and the fuel pressure regulator spring does go weak over time. Both can be replaced.

Third (and I don't mean to sound condescending here) are you sure you didn't put gas in it instead of diesel? That is a more common thing that many would care to admit..

Yes it was the regulator not a sensor poor choice of words on my part. The truck has 108,000. I have had diesels going back to 1988 and no I did not put gas in the truck. It also went through 9 injectors all at once. In the letter it shows that the # 5 was replaced and on just test time it wiped the new #5 out too. Yes parts go bad but why ot what caused the entire fuel systen to go all at once. Is it normal wear or cause and effect?

so why have you not yet given any details as to what engine? ? ? assuming its a chevy do they not also have some sort of water in fuel indicator. did you get the "contaminated"fuel sampled. then you might have a claim against the fuel supplier. the onus on you would be to prove that your fuel system had been maintained to factory specs and that no part of the condition was preexisting to the fill up. i wish you well

Its a 06 GMC lbz. The dealer pulled the tank and said it was loaded with water which I have on the repair order. The tank was cleaned as stated in the letter to them. The fuel was dumped into a dump tank at the dealer contaminating my fuel samples. The insurance co came out and I'm guessing 1week to 1 1/2 week later and took a sample off the top of the tank which we all know water doesn't float in fuel. They sent the sample out and it comes back clean. I'm trying to find out is it common for a entire fuel system 9 injectors fuel regulator and injection pump to go all at on time. Is this a common occurrence (wear and tear) like the insurance co. is saying or is this cause and effect? I maintain my truck and there were no pre existing problems before fueling that morning. I had a amsoil bypass for the extra filtration and an air dog on for the fuel filtration. Unfortunately for me I never kept records of the maintenance I did never thought I would need to prove I service my truck. Lesson learned I now have a file for every penny spent on it.

I didn't even notice this was not about a Ford 6.0. This needs to be in the GM section, not this one.

Why would it matter which section its in. The basic question is it common to lose an entire fuel system all at once under normal conditions. Has any one ever herd of this happening under normal conditions or to lose the entire system all at once does some thing have to happen to it? I'm looking to try and back up what I believe that its not common place for this kind of failure to happen with out a cause.
To clarify each exhibit is a dealer receipt
I was hoping that people would read the sequence of events and give an opinion on what they think happened.

This ensures members to be able to give you the best answer. While most newer model diesel engines fuel systems are similar the 6.0L PSD is quite different than any of the GM Duramax fuel systems. It is possible for something such as water to damage an injection pump and injectors, the Dmax using the CP3 to pull fuel from the tank then send it to the fuel rails. While the 6.0L does not have an injection type pump and is a HEUI system that uses the HPOP to build pressure.

Thread also moved to LBZ DMax forum.

The Air Dog should have taken the water out of the fuel, unless the Water separator was never changed, emptied or there was so much water in the fuel that it over whelmed the Air Dog. Did the WIF sensor on the stock filter detect water?

The filters on the air dog were only a couple of weeks old and if I remember right the stock had around 60% on the evic. I also ask the dealer why the light never came on and if the other truck in for the same if the light came on. He didn't know why and the same for the other truck. They showed my a container with the water in the fuel. I'm positive on what happened. I posted the scenario to find out what conclusions others would have by reading it. To find out if others have had complete system failures for no apparent reason meaning good fuel and maintained. Its my guess the answer is no

if the dealer or mech is willing to make a statement you might have a claim against the service station, or insurance for selling bad fuel. same as if they pump gas into a diesel

complete fuel system failure is not impossible but very uncommon, the AirDog should have picked up the water, then the factory filter should have picked up water as well, there must have been A LOT of water in the fuel to cause that much damage

Is the truck running properly again or still pending repairs?

It was loaded with water according to the dealer. Its all noted on the repair orders.
As far as the truck I quit at $9700 and traded it in as is. I was with out a truck for 7 weeks. I'm self employed and couldn't afford any money out of pocket or more time down. So I cut my losses.
The thread isn't doing what I thought. I was hoping people would read it and give opinions on if it was caused by the water or if it could just be wear and tear. I don't believe its normal to lose everything in one shot not to mention the brand new #5 injector that went bad just from running it while on the star scan. I'm appealing the decision now and next will be court. I just don't believe its wear and tear or lack of maintenance. I maintain my trucks well. I spent the money for the extra filtration to protect my investment. I just made a mistake on not documenting it but I never thought some thing like this could happen

No this is not normal wear and tear, this is caused by the water in the fuel, no doubt, my truck has 110k miles on it with no issues with the fuel system yet, all injectors are +/- 0.xx-2 no more or less

when you have all injectors at +/- 12 on an LBZ you have major problems, the LBZ injectors are hardly ever known for failing

All Forums have different thread sections for a reason posting in the proper area is more beneficial to you as the person posting the thread/question as you will have more Members responding to your question if posted in the right forum section.

I read your post why did Salerno GMC Dealership, Randolph, preform the first diagnosis and not preform the repair?
First of all water in fuel does not cause a FPS all of a sudden to quit working as well as one injector there has to be more to this situation than what is posted.
3 different shops and not any of them could fix this problem?Seems Odd as it was a all of a sudden problem as you described it happening.Why would the the third shop be the only one smart enough to check the all the injector balance rates?Than tell you all the other injectors need replaced?
Good luck with insurance they are not stupid and may very well wonder the same thing.
Water does not cause injectors to fail that quick.

It was taken to Salerno which was the dealer I bought it from. When the gave me pricing on the parts they wanted $613 for the injector and started to tell me that this was going to be a very very expensive fix so I took it to a local diesel repair shop. Salerno turned out to be right. The local shop replaced the parts but the truck still had problems and they didn't have the computer to continue working on it. I took it to Gearhart to be repaired. Everything is documented on the repair orders and receipts from the fuel receipt towing bill to the finale estimate for the injection pump. Gearhearts price for the injector was $485. When it broke down I never had any intension on turning this into insurance thats why we didn't just go and replace everything all at once. I was trying to save some money and just fix what was broken but when the bill started getting real high Gearhart suggested that I turn it in.
If water doesn't cause injectors to fail what would cause everything to go bad all at once and the #5 was a brand new injector. Prior to fueling that morning the truck ran fine. Only common denominator on all the parts that went bad is the fuel.

Did you keep a sample of the fuel and send it to be tested for water content?If it is indeed water that caused all these failures then it will help you with the insurance claim.
Was the any rust on the sending unit lines and support inside the fuel tank?Fuel filter?injectors that were replaced?
