I totally agree that the issue is not primarily water related. It may have an impact and is not a good thing for sure. The additional effort to dump water before it can get to the pump is a good thing and if we can do that cost effectively and not impact on the Ford warranty then why not go for it.
From what I have read the main cause is pretty plain and simple. It is the lubricity in the fuel not matching the pump manufacturers required spec. They, Bosch, want less than 460 and preferably 380 but the fuel supply in the US is pegged at 520. Fortunately in Canada it is 460 which is closer but still not perfect.
Solution is for Ford to use a pump that matches the fuel supply. I think that is the key. The Bosch pump is what it is. It matches the fuel supply in Europe and Canada. It was incorrectly selected to match the fuel supply in the US. Ford needs to change the HPFP it is using .... plain and simple. The specs for the diesel fuel state 520 for the US and this is not new. Ford needs to source a pump that will run and be reliable at 520. I guess another option is to advise us all to use an additive in correct proportions and make up to meet that requirement. Last point. I have also read that too much lubricant can cause other issues.
Tell me I am off on my thinking here ....... Please.

I'm not 100% sure but the Ford Cetane boost does not contain any additional lubricity and yes you could over dilute with no impact. The cetane levels going up is a good thing. I think you would want to use something like what Tom recommended earlier in this thread I believe. He actually talked to the manufacturer.
The too much came from a site that stated too much lubricant can cause clogging of the injectors. Not sure at what dilution etc.

Strange, my bottle of PM-22-B does not state that. Only says Cetane Boost and Performance Improver. Nothing else on it. It does say new formula and ULSD compatible. Is it possible you have an older bottle? The B is for Canada as the label is in liters. I am thinking the PM-23 includes additional lubricity. Need some answers on this one for sure.

Diesel fuel quality is critical for reliable engine operation. Motorcraft® Cetane Booster & Performance Improver, PM-22-A (U.S.) / PM-22-B (Canada) can be added to improve fuel economy, starting ability, and reduce engine wear. The water separator should be drained monthly (at least) or when the “Water in Fuel Lamp” illuminates. Biodiesel fuel must not exceed 5% (B5). To avoid cold weather fuel gelling, add 6 oz. of Motorcraft® Anti-Gel & Performance Improver PM-23-A (U.S.) / PM-23-B (Canada) to every new tank of fuel.

PM-22-B is not an anti-gel. As dbc001 stated it is just a labeling difference due to Canadian fuel being pumped in liters instead of gallons. I can only imagine some of my employees standing at a pump that dispenses liters and trying to figure out how many ounces of additive that they need for 95 liters of fuel!
Thanks for the clarification.....So Ford does not offer an anti-gelling. Eitherway....IT DOES A BODY <engine> Good!!!

Thanks 720deere .... now for the big question; does either formula include a lubricity improver?
Would like to get feedback on the post earlier in this thread regarding the selection of a pump by Ford that does not meet the documented fuel supply.
