I debated for literally years about selling my 6.0 that I had for 10 years and NEVER ONCE saw any repairs EVER and getting a 6.7.I knew going into it all the issues with the CP4.Alot of my decision was based on sales and simply how many were on the road.After I saw the 17's come out and the hot shot guys were buying them I knew I was buying one...As now i have a 17 6.7.

My point is...good news travels,And bad news travels three times as fast....If these pumps were half as bad as people make them out to be there wouldn't be half the trucks on the road you see day in and day out.

 

So the difference in the new pump is that it is a asymentical in stead of symmetrical . Anyone want to decode what that means.

 

Here’s the best pic I could get of my 2020 CP4. There are 4 small dots.

 

I tried to look at mine and could not figure out where the dots would be. based upon the above pic I will try again.

 

You are correct, some folks will have problems, some folks will not.

I have personally seen metal flakes in fuel filters on prior trucks so what ever the factors are to put someone in the potential risk group is prevalent in my area.

suspect factors

a. Poor quality fuel
b. Fuel that does not meet the min lube spec
c. Water in fuel from either condensation of the truck tank or condensation of the station fuel tank
d. Fuel starvation from cold weather waxing
e. Water separator technology in both trucks and station fuel dispensing systems that dont work
f. Marginal filtration of truck fuel systems
g. Fuel pump internal parts that can rotate out of sync
h. Fuel flow design of the pump that results in fuel that lubed the pump bearings goes directly to the injectors unfiltered
I. A recirculating design of the fuel system that sends contaminated fuel back to the tank and cycles thru the fuel system
J. No obvious way for an operator to know they are under degenerating conditions
K. Aluminum internals within the pump that is susceptible to cavitation from air entrapment of the fuel

it would probably cost 2000 in parts to mitigate most of the above with state of the art technology

1. airdog or pass to reduce air entrapment=$800
2. Spe disaster prevention kit=$400
3. Energy metering valve =$250
4. CAT 2 micron filter (if you don’t have (1) ) or S&S liter manifold with a CAT filter =$250
5. A 1 or 2 micron filter solution after the pump but before injectors. No official product offering here , but converting a high performance 1 metal micron in line filter would not be impossible . =$200-$300
6. a low pressure indicator to let you know your lift pump failed . = $90 if you have the SPE DPK since the SPE DPK is predilled with the needed ntp port
7. one of the after market cables with npt manifold for low fuel pressure sensor if you don’t have the spe DPK . =$75

ford knows something is up. Starting 2021, a née pump with less aggressive cam lobes will be in use.

 

I suffered catastrophic fuel system failure in my 2012 Chevy Duramax, within 6500 miles. I have had 5 pickups with a CP4.2 since then, and one with the Siemens K16, also known for grenading and wiping out the entire fuel system. Then I look at the 6.7 Cummins and they have also chose this pump for the new engines. For the sake of noise, and emissions. Vehicle manufacturers and engine manufacturers alike have been known to make poor decisions based on cost, noise, emissions, etc. The CP4 cannot be as bad as the internet thinks, but it is weak. Compared to it's popular predecessor the CP3. That being said I won't shy away from a truck with a CP4.2 nor do I think anyone should. I'm sure some of the redesign of the internals on the pumps addresses the inherent weakness of the pump as well as improvements due to the max pressure Ford is now demanding out of these pumps compared to prior years.

 

Would 2020 model years be able to adapt this new pump found in the 2021?

Shoot, I might have held out and got the 21 instead of the 20 I just picked up!

Oh well...

 

I had no idea about changes to the pump for 21'.

 

What are you talking about for the **S&S liter manifold with a CAT filter ??

I know what you mean by the CAT filter as you can get a replacement for the stock plastic engine fuel filter. I'm thinking you meant H&H.

Edit

I'm thinking of my buddy's gun shop. H&S I meant.

 

I just priced that new Ram Wayne's boss picked up and those stealership people have lost their minds (ditto Ford). I'm a multi-business owner, not poor, but dear lord when is this TOTAL GOUGE / UP THE TRUCK BUYER"S YOU KNOW WHATS going to stop?

These clowns at Ram, Ford, GMC, Chevy etc have been running their outrageous pricing 5x-10x inflation for some time..................the correct posture for truck buyers is start to bend over the minute you enter a stealership's location..............cuz they all see suckas coming (about to get drilled)

 

The sticker on my truck was $68.2k . I've seen low trim level 2020 F450s for anywhere from $69k to 72k ish...

I don't think that's bad. My last new truck was the 96 listed in my sig. Took me 20 years to afford another new one. I sold my childhood house in order to buy it.

When I was a preteen, it cost just under a dollar for a Small pop, cheeseburger and small fry. Now look at the cost of stuff. Look at the cost of ammo. How about the cost of groceries?? EVERYTHING has gone up. Look at the price of tires. Sickening... It is what it is. Hence, why I have plans to make my F350 last me. Unless I become independently wealthy.

 

I have to disagree with the "it is what it is" statement, only because I hate the words and it is what is wrong with the majority of the country now days. End rant, I agree with you on pickup pricing, it's fair considering what you get compared to back in the day. Albeit a lot of the things pickups come with are unnecessary for most. Sure is nice to know you can get a massage in your pickup while driving down the road after a long day at work, or protesting, or whatever the heart desired to do that day. What was once reserved for the ultra rich is now in arms reach of the middle class.
Back to the CP4, I hope they fixed it, but I would highly question it, being as the base design is inherently weak.

 

Let's just say that it applies to the subject of truck prices as EVERYTHING is going up. I see your sentiment and point taken bro.

I do use it often but not for what is currently going on in our country, to be sure.

For example:

If it's got t1ts or tires, you are going to have problems. It is what it is...

 

Couldn't agree more! Hope all is well.

 

Yes sir! Sure is, thanks. Hope things are well with you.
