Updaate, after finding aluminum in DFCM I have had numerous discussions with Ford diesel tech at multiple dealerships in the south La area. All but one concluded the only source of aluminum could be the HPFP, of which I am concerned. However since the truck exhibits no performance problems at all, they are at a loss as to why...so okay, one tech stated that based on his experience he has seen aluminum and rust come from the fuel tank level mechanism, and thought maybe that is the problem, but still has to suspect the HPFP too, but...it still runs great. Realizing the possible down side cost, he suggested pulling the PCV and VCV since they are relatively easy, and it will be a $740 charge to look at them, which will also let Ford off the hook if there is any indication of rust at all, even though it still runs...I sorta agreed and since the truck was running fine, the dealership would be short handed over the holidays, I decided to run about 1,000 miles of planned use over the holidays without the trailer, and then check the new DCFM filter after the holidays. This I did, and the filter had only a couple of specks of aluminum in it. Otherwise the filter media was pristine and the truck still running strong....until day before yesterday when it threw its first real code since new....CEL came on in NOLA, I had a heart attack, engine still running fine, drained filter on the spot, nothing but clean diesel again. Restarted and drove toward home and CEL went out. Yesterday CEL came on again briefly, truck bucked two times and power went down and the CEL went off and truck continued to run but with about half power. Back to dealership and today am told the EGT sensor is bad and will be fixed tomorrow morning. So now since it still runs, I am going to keep roll the dice for another 1,000 miles since I know there has never been DEF in the system or had a water in fuel warning or physical presence of water when the DFCM has been routinely checked. I will again pay $87 for an new set of filters and and check one more time before decide to pay to have them pull the PCV and VCV and look for contamination, or just dump the truck. Its just irritating to realize I may, or may not be flirting with a $12k repair when the only indication is the original aluminum in the DFCM cause I still like the truck....crap....hope I dont hear...'told ya' since I am sticking with it for a while longer....sorta against my better half's judgement.,
I believe I read another member here had a similar situation. Aluminum specks. I think he was saying it was just a matter of time....It's a shame they can't make a better water separator.
Seems to me, that you could get aluminum specks from the fuel nozzle going in and out of your filler neck, when you fuel up. Or very possibly from the hose coupling that the fuel tanker used when they delivered the fuel. Almost all the fittings on those tankers are aluminum.

Fuel pumps(at gas stations)have filters installed to prevent contamination such as this. Apparently they need water separators also. I think before this is over we'll see something done at the gas station level to prevent this, because the insurance companies are not going to continue to pay out $12000.00 every time a Ford fuel pump craps itself due to water intrusion. On the other hand, the fuel stations/companies are going to say there is no more water in their tanks today than there was 5 years ago, so Ford may have to take some responsibility and own up to the fact that their new engine is just more prone to water damage than past engines. My 7.3 uses the same fuel from the same pumps that you 6.7 owners buy from, yet we don't hear of these issues with the 7.3's. (Ford, are you listening?) Obviously this is a weak link for such a strong engine.

Hi dayner,
I'm happy to look into this for you and see how I can help. Send me a PM with your VIN, dealer, mileage, daytime phone number, and full anme; I'll get to work!

Gotta love the 7.3 guys, they try so hard.

Pump is not the problem. It is the lubrication (design).

How can the filters be clean if it is coming from the tank? I would think you would see it there since the system recirculates the fuel? I am thinking of adding the diesel site filter set up .have you been adding fuel additive.

You 7.3 guys love to come up to the 6.4 and 6.7 forums with your "my 7.3 has no problems with......." Crap. If the 7.3 had a common rail fuel delivery system you WOULD have these problems. The 7.3's injection system, while dependable, it's not going to work on today's engines. You simply could have said "hey ford, you need to fix this" but you do what so many other 7.3 guys do, you sneak that comment in about how your 7.3 doesn't have those issues. The bottom line is the 6.7 totally smoked any diesel ever put into a ford and it is very reliable and well designed. The 7.3 had it's issues in its first couple years of manufacture too and those international engineers didn't have to build to the standards that the 6.7 liters engineers had to build to.
Don't get me wrong, I had two 7.3's but I don't miss either one, especially when hooked up to a trailer.

Cratos. How can filters be clean?...easy, the fuel in the tank is not dirty enough to show anything on the DFCM filter after only 1000 miles this time, and the engine mounted filter has always been clean on every filter change so far, ie the DFCM filter does a good job of filtering solid particulate. So, the problem is not dirt, algae, trash etc that has accumulated in the tank. Yes, about 2/3 of the fuel pumped to the engine mounted filter returns to the tank from the fuel rails as it really is used to lube/cool the HPFP. Why is there not a lot of Al in the DFCM on this change, that's a good question and since the truck has always, is still running strong (except for the CEL/sensor fixed yesterday, by the way it was fixed promptly under warranty by the local dealer that required replacing both the sensor and the harness connector), thus my limited confidence (actually hope) that the problem may not be the HPFP at all but possibly the tank gage assy or something that did come in thru the tank filling, maybe a few thousand miles back before the previous filter change...hope so at at this point, but then as we know, a ton of hope and $5 will get you a cup of coffee these days. And yes I use...Ta Da! "New Formula" Ford Cetane Booster and Performance Improver by 20 oz bottle title; PM-22-A FIR 178699 by fine print on back label pretty religiously. Have always used the PM22 in this truck. Used Power Service in the 6.0 until the EGR cooler split and trashed the engine, but a least it was buried with really clean injectors.

Well, pardon me for posting on the 6.7 page. I know us "7.3 guys" aren't worthy to be on the same level as some of you.
"If the 7.3 had a common rail fuel delivery system...." Well if frogs had wings they wouldn't bump their ass when they hop, but they don't so lets not compare apples to oranges. I'm not trying to compare my truck to yours.
Fact: The 6.7 has expensive issues when water gets into the fuel system.
Fact: The 7.3 does not. (Not to the extent that it cost in the neighborhood of $10-12K to repair it. For that kind of money I could put a new engine in it and have change left.)
Fact: I buy my fuel from the same place guys with 6.7's do.
I was just pointing out that I don't believe the insurance companies are going to eat these repairs indefinitely, and if the problem is widespread enough that Ford may have to assume some responsibility. It appears that some of these trucks have not even given a "water in fuel" warning light even though they have encountered water at some time.
So pardon me for mentioning the lowly 7.3 on the same page as your wonderful 6.7. It's superior performance is only matched by your superior attitude.
Well spoken badbart......Nothing wrong with being happy to have an old polluting but very reliable and most all the kinks worked out 7.3. Mine is a 2003 (last year they made them if I understand correct), and I could not be happier to know I have the last of the (old) engine's. If for no other reason, just to know I/it is not having to conform to the ridiculous emission standards that the newer engines have to. And that's probably what is the cause of most of the problems with these newer engines. Unfortunately, I cannot do anything about the quality (or should I say lack there of) of the fuel at the pump. This ultra low sulfur (15 ppm) fuel is another part of the problem, So I try to combat this lack of lubrication with the addition of a bit of two stroke oil at each fill up. My (old) 7.3 was skipping for a while , but since I started adding the oil the problem seems to have gone away. Could be just a coincidence but I may never know for sure.
