I had a diesel mechanic at the local DC dealership tell me extended idle time on the Cummins is not recommended and that it builds up carbon on the injector tips and will cause you to lose an injector or worse burn a hole in the piston. He also told me to run it as hard as I could.

Dirty fuel is a common one. I have done nothing with my stock 03... but all my injectors were just replaced.
There are vents on my fuel tank I should be putting a filter on, or something? Can't I just cap them (I suppose not because I assume you need them for when you fill the tank at the station, no?). Isn't there some kind of vent line that runs up to where the fill cap/filler neck is?
Should I do anything else? I don't have the money for an AirDog or FASS right now but perhaps that would be the best thing...

Psycho...This thread may help.
Also here is a good source for 2 micron filter systems.. http://www.glacierdieselpower.com/de...dept_id=08-001
Hope that helps.

The top of your fuel tank will have 2 vents on it. (maybe 1) I think they are evaporative emission vents for the gasser version of our trucks. Get some ¼ inch fuel line, attach it to the vent(s) and run the fuel line to a gas fuel filter you mount somewhere under the truck. Just go to the autoparts store and look for some filters with 1/4 inch hose barbs; even a lawnmower filter should work.
Mine had one near the front and one near the back. These vents are in depressions in the top of the fuel tank so dirt and water can get in. There was some recall for some trucks but all they do is put a 6 inch line on the vent.
Have a look for yourself; you won’t even believe they shipped trucks with open vents.

There is a recall for this problem, so if you don't feel like doing it just take it to the dealer. Get a 5 micron drop in filter from Baldwin for the stock setup and that will help in the meantime untill you install a decent 2micron setup.

Here is the TSB Recall for it. I thought it was for all year models, but after looking at it again....You are correct Hounddog. It just doesn't make sense that they would only do 06 model years. What about 03-05 models? They are the same as far as I know.
I corrected mine using info from that link of the thread I listed in my post above. https://www.dieseltruckresource.com/...d.php?t=117209 It is alot better to install hoses, T-them together and put a filter on it than Chrysler's fix anyway, imo. And while you are doing it, you might as well do the Vent Tank Fix and add about 5 gallons of capacity to the tank too. http://www.glacierdieselpower.com/de...dept_id=02-001

If you run a 2 micron filter they are way more likely to jell in the winter, so you need to run more #1 diesel.
Don't forget heat can cause damage to you injectors too. Fuel cools your injectors and if you run your truck down to its last gallon the fuel will get hot.

Not to rain on anyones parade but I kinda know a Duramax tech at a Chevy dealer.He's been at the Diesel thing since early 80s at the same dealer.Does nothing but diesel repair there.Anyhow we were talking injector failures,filters etc.G.M. had a recall a long while back on the filter system.The Duramax system is very much like the Dodge.Anyway tech said before or after the NEW filters and system or aftermarket filters the amount of bad injectors he has been seeing(which is weekly to several trucks weekly) has NOT decreased.I guess time will tell on these 2 mic systems etc.

so are all these guys with aftermarket filtration systems gelling in the winter? would just treating the fuel at every fill up take care of that? what if you used the stock filter and housing and added the aftermarket filter after it, that way you could still have a fuel heater. or would it still gell in the short time from there to the aftermarket filter?

That doesn't really make any sense, the amount of fuel in your injectors, CP3 pump and rail itself is the same whether you have 2 gallons or 30 gallons in your tank... what are you getting at ? I agree fuel can help cool the injectors in the sense that it's a substance that absorbs heat -- but not nearly as much as when it is atomized in the HPCR and the injectors -- it's a vapor at that point... so even if fuel pressure in the HPCR gets lower when you have 2 gallons in your tank (versus 30 gallons), it still wouldn't matter very much. And if your fuel pressure in the rail is lowering as your fuel tank empties, you've got a problem...

Unused fuel passes from the injectors, through a passage in the cylinder head where it picks up heat and returns to the fuel tank. The theory is, with a large amount of fuel in the tank, the fuel won't get as hot before it's return trip to the injectors.

When you get down to those last few gallons the fuel will get hot and if you are drinving in hot weather I believe their comes a point where you can actually cause damage to the injector. I have no proof of this but it does seem that some of the guys that have injector problums do run the fuel tank down to a few gallons on a regular basis. Could be a small factor.
My combine has a fuel temp light and the only time it came on it was 105 and I was very low on fuel. The owners manual states to shut down machine and add fuel or fuel system damage can occure.
I do believe that the 6.4 powerstroke has a fuel cooler. Must be a reason.

You also have to think about when there is only 2 or 3 gallons of fuel in the tank, both the contaminates and water are in a much higher concentration! More of it going into the fuel filter ( hopefully ! ) or worse.....making it past the filter!
