I've bought fuel from Md. to SC. at all kinds of stations and nary a problem or drop of water. I even put a 10 micron filter with water separator on the 63 gal. aux. tank I have in the bed and that has never produced a drop of water either.
So how is Ford denying claims for this when t has an improved fuel water separator in the late model system. How is water getting to the parts that self destruct when water is in the fuel? They are basically saying you put bad fuel in it and our system can`t filter it out so you pay for the repair. The amount of water constantly in the fuel would have to be significant and your water in fuel would be on after every tank full. I call bull and Ford is just passing the buck. So what are you going to do when the dealer has your truck all torn apart in the shop tell them don`t fix it and I`ll tow it 1000 miles home to fix it. Nope and they know that.
I've been reading about the disaster prevention kits all weekend and all of them can not prevent the CP-4 from destroying it`s self just prevents the shards of metal from getting to the injectors or back to the tank at best a 20 micron filter is suppose to stop the contamination but the final fuel filter is 4 micron on the engine from the factory. So how can bad fuel even get to the fuel pump to begin with.
I`m paranoid that the truck is going to leave us stranded in the middle of nowhere now and there is nothing you can do about it to prevent it.
I guess I`m looking for people that has had a CP-4 problem and their experiences in getting a timely repair done.
Shoot this sounds like the crap some people put up with at the RV dealer.

I am pretty sure as explained by the man at SS Fueled that water, fuel quality, and additives have little to do with the CP4 failures. It is a design flaw and it is likely that Ford "coating" an internal part will prevent it from turning and causing the failure. Time will tell...

Lack of lubrication (primary cause), water and rust (ie; fuel contamination) is what the people on Fords forum boards that this has happened to say. Ford says bad fuel causes this failure and denies the clam to the tune of $10,000 dollars. A few have sited the piston in the bore of the CP-4 has turned and destroyed the pump sending metal every where but that is a warrantable issue. But the contamination issue is primary cause and S&S and others with these disaster kits is only a band aid to the problem. It is preventable by a more robust fuel pump coatings and even better fuel filters/water separators that can stand up to our crummy diesel. Bosh has stated that we don`t have this problem like you Americans do. Their diesel is held to a much higher standard than ours. As read in an article I can`t find right now or I would post it, it`s out there maybe you can find it.

I just want the truck to run like the trucks I`ve had all my life. It sounds pretty stupid to buy a truck based on what fuel pump it has now doesn't it.

I have a 2011 Power Stroke with 142,000. As one poster stated I try to fuel up at high volume stations and regularly use Opti-lube as an additive. 6 months ago I installed a FASS lift pump.

Separating out the water is the main issue with Ford. Have you seen the size of my 2017 water separator it's huge and I have never seen one drop of water from it. Of course I refuel only at truck stops and I change fuel filters at 15,000 vice recommended 25,000 miles.

Soooo.....some here swear that fuel lubrication is the problem and stand by it. Others say BS...its the pump design and nothing you can do to prevent it.
Hmmmm....what to believe?

Believe the guys that work on these trucks this guy from S&S Diesel is one of them. Believe whatever you want to fuel, water, etc. The CP4 is flawed from the get go and every time you drive a truck with one be it a 2011 to current 6.7 Powerstroke, a 2019-2020 RAM 6.7 Cummins or a 2011 to 2016 LML Duramax you are playing roulette with $12k on the table. RAM has gone back to a CP3 and issued a recall on the 19 and 20's. GM uses a Denso HP4 on the L5P 6.6 Duramax. Ford continues with a CP4.2 and even if you wanted to you cannot retrofit it back to a CP3 it won't fit. At least the LML Duramax can be retrofitted with a CP3.
