Currently, the Ford 6.7L CP4 to DCR Pump Conversion will fit 2011-2019 F250-F750 trucks, with future plans for 2020+ compatibility.

Interesting that the lines and bracket are another $70.

Ordered it this morning. Once installed I will feel 100% protected in case that CP4 pukes. I take good care with fueling so if it goes, it won't be from lack of prevention.

I feel the same about my truck and fuel.

When I got in the market for a Super Duty, the 6.7 CP4 issue weighed heavily on my mind as that is a HUGE expense when it failed. When I finally bought one, the first thing I did was install the SPE. It gave me the peace of mind I needed. Anything else on the engine is cakewalk for me, the fuel system is one item I do not want to mess with.

OK, haven't been on in a while but I'm now at 110,000 miles and thinking about CP4 failure.Two questions, how many of these pumps are blowing up and taking down the fuel system, how big is the problem. Am I reading this right, I want the S&S DPK 2.1 and I can install it myself in 4 hours or so. Well, I'm 80 now so maybe 6 hours for me.

I don't have one now, but will probably do one in the future. Just cause I would be kicking myself if my HPFP takes a dive and I could have done something about it.
Lastly, more power to you doing this at 80!

You see various numbers for the failures. I can't point to a source and say this one is an authority. But the less than 1% seems to come up more often for a pure part failure. That ignores the failures from putting DEF or Gas into your fuel tank.
I've owned four 6..7L trucks. 2011 that I put 150,000 miles, 2015 that I put 100,000 miles on, a 2017 that I ran 92,000 miles and the fellow I sold it too, now has 140,000 miles on it and my current 2020 with 77,000 miles. No problem with the HPFP on any 0f these trucks.
I also know of others. My plumber that I use, has 220,000 miles on his 2015 and it is still all original. And you see the Hot shot drivers on internet with trucks in the 300,000 to 500,000 miles with original pumps.
I've taken the belief. You buy good fuel, drain your fuel filter on a regular basis. Change fuel filters every over oil change with real motorcraft filters. If I had spent money on every truck I've owned for disaster kits, I would have paid more than just doing the full repair. So Maybe in a sense, I'm self insuring for a disaster that my truck insurance may or may not cover.

Actual pump giving out because of a defect, very low. Pump going out because of contamination, very high. Chances of your pump failing, Very low provided you use good fuel and a lubricant. Even without the lubricant, still very low. The pumps do not like water, and especially hate DEF. The biggest issue is lack of separation between the fuel pump crankcase and the pump heads. It allows debris from the crankcase to get into the HP fuel rails and injectors. If Ford had designed in the DPK from the start, the pump issue would not be as scary as it seems and not too big of a deal like it is. Foresight on Fords part would have prevented Reputation that it has.

Thanks guys
Not sure yet but these answers are helpful. No def getting in my fuel. Third diesel super duty so not likely to put gas in. Every gallon of fuel ever has Diesel Kleen added. Fuel filters at 15,000 since new so I guess I’m doing what I can. The only other move would be the kit. Thanks for the help.
