2004 ford F-550 running problem

My boss has a 2004 Ford F-550 with the 6.0 liter diesel. he has had it in the shop 10 different times this year with fuel, injector, tank problems. is it possible that the ethanol that they are putting in the fuel is messing with his truck. ford says no but is that just their way of covering their tail? he has had the tank dropped and cleaned once. it was full of a brown soft debris. not rust just a like fungus type. he had to replace several injectors and on the fuel pump on the frame there is a plug that you loosen with an allen wrench i pulled it the other day and this grey soft shavings came out. they had the consistancy of lead. real soft and smeary.

he is now considering just buying new tanks and putting new tanks on the truck . it has a 30 gallon rear tank and a 18 gallon front tank. ford will clean the tanks for 500 each. they say that there is a liner in them is that possible? also is it possible to get a plastic or fiberglass tank instead of a metal one? to maybe advert this from happening again? just trying to figure this out so that the truck can go to work and do what he bought it for instead of it being a planter.

Any ideas?

A bacteria will grow in untreated diesel fuel left for long periods of time. Here is a good article on the subject.

Diesel Fuel Bacteria Problems

If the truck has not been left sitting for extended periods, then the source of the fuel should be very suspect. Note that this bacteria lives in water and feeds on diesel fuel. This is either happening in the fuel tank or the storage tank of the fueling station.

Instead of replacing the tank, maybe just cleaning it and using a fuel tank coating like this Eastwood product will work.

This isn't the famous "tank delamination" issue, is it?
