CP4 bypass kit

The complete repair kit is $3300 and the book time is 18 hours so I think that 10 -12 k number that we hear of is BS. More accurate would be to say it keeps a $1k repair from becoming a $6k repair.

Edit: It could be that if you just have your truck towed to the nearest Ford dealer and pay the bill when its time to pick up the truck you'll be dinged with a 10 - 12k repair bill but I know that is not how I would handle it if it were my truck.

But you are not the average soccerdad consumer who only knows that his new Ford Powermax is kooler than his neighbors Durastroke....or whatever they call them things. And that its def, like def jam on MTV back when he was in hi school.

For that dude, it's $10k as soon as the tow truck pulls his new Durapad, or was it Powerpad, sht I forgot, truck to the stealer.
There's mechanics in the back Indian Leg wrestling to see who's gonna get to milk some sucker for twice the going rate!

As I'm sure you and other guys like Fish, 12V, Scott, Shiner have seen, you can prevent, fix, advise, and most importantly understand.
Soccer dad don't understand...
He!!, I had to fix the bike tires on my nephews bikes, because their dad couldn't figure out how to plug the leak around the air thingy!
He has enough money to float the payment on a new truck. How much you think they'll charge him??

Exactly! The kit does not keep the CP4 pump from failing, it just keeps a $1k repair from becoming a $10k repair. This is why my brother was about to install the kit before he traded in his truck. His pump was showing signs of failure and he did not want a $10k repair bill like my cousin and another friend had in their PSD's. At the last minute he decided to just trade it in on a CTD.

Repair kit EC3Z-9B246-B price varies greatly from the dealer to online stores. Then there is the factor whether your injectors and pump are still a good core or not which could increase the cost to $5k. In most cases, not all of the cores are good enough to return so you will be paying extra for that.

Labor rates also vary at our several Ford dealerships depending on severity. You also have to add time for dropping the tank along with environmental fee for disposing the diesel. This cost varies depending on how much fuel was in the tank. You also have the cost of a fuel filter change(which does not come with the kit) and to flush the lines from the tank to engine.

Add it all up along with tow charge and a 6-10% sales tax then you are very well sitting at or near $10k based on on the repair orders in our shops.

Edit: The cost of the kit varies depending on year.
EC3Z-9B246-B is from 2011-2014 and cost around $3,300 plus core
FC3Z-9B246-B is from 2014-2016 and costs around $4,300 plus core

Last year, my company has sold over 50 of the EC3Z-9B246-B and 5 of the FC3Z-9B246-B.

Am NOT a diesel person, but am very interested in this thread...

Now that gassers are coming out with DICI (no spark plug) and assuming much higher gas PSI's...do they have a high pressure fuel pump similar to the diesel HPFP?

Learned a ton on that Bosch HPFP during the couple years reading up on a form members unfortunate experience

Pure dumb @$$ design by Bosch engineers. Made worse by management sticking with the original architecture and forcing band aids

Dumb @$$ by not capturing the piston to the cam and only depending on the fuel's PSI to force the piston to stay on the cam (caged desmodromic valve actuator would have been much better). Ditto using diesel as both lube and coolant (engine oil would have been much wiser). Ditto stacks of piezo silicon chip actuators in the injectors (glass is brittle).

Am in the hunt for info on the new gasser DICI fuel system, but not enough yet. Hope they didn't back themselves into a corner like the Bosch HPFP

I think it's a good addition (without data to back it up personally) ot insurance. $300 vs $10k is an easy choice in my mind. Like dropping $200 on a secondary fileter for my 5.9 Dodge. Did lack of filtration kill my injectors in 120k miles? Idk. Will I put more than another 120k miles on it? Thought i was back in 2014, but now she sits and only gets one oil change worth of miles a year.

What I wonder about the bypass kit, looking at the schematic...
Before the kit, all the fuel ran through the whole pump providing lube (and cooling?) to the pump. Then when the pump spit it's guts (which has been revised in the CP4.2 design), the guts went out with the fuel to the rail.
With the new design, does the pump just run on whatever fuel is left in there? Ie, getting dirty/old/contaminated?

Also, why has S&S not marketed a kit for the Duramax, same pump, same issues (but purportedly better warranty coverage)?

That’s a good question.

Nobody really knows if any improvements have been made to the design but we do know that improvements have been made to the fuel filtration.

Some are even saying that since Cummins is now using the CP4.2 pump that improvements probably was made with no data to back it up.

Sorry if this is going off-subject but does anyone know if replacement HPFP's are better or modified in some way to help prevent this?

While the newly designed CP4 pumps that go onto the 2015+ trucks appear to be more reliable, you are SOL on the 2011-2015 trucks in regards to Ford doing anything. The bypass kits do not seem to be that common on this site because most here seem to think that their brand makes a perfect truck and modifying it is heresy. Outside of these forums in the diesel modding world, these kits are very common. My brother was going to do it on his 2012 F350 before he decided to trade it in on a 2014 Ram 2500.

Since you’re bashing the owners of their perceived perfect truck why are your advertising your brother trading a truck for a 2014 Ram.

Sounds like your brand marketing again!

Awe, did someone get their feewings hurt because they can't handle the truth.
