BEST MOD for Ford 6.7 Powerstroke That Could Save You Thousands! S&S Diesel CP4 Bypass Kit

[@michaelbenoit248]

Just installed the Gen 2 kit on a 2019 F550, & from doing the kit the instructions are taken directly out of the Ford IDP service manual for removing the 2 intakes. The hardest part of the whole kit was the 1 but under the high pressure fuel line for the fuel filter cup. Took 30 min to get it out. If you are doing this job go watch the S&S video because they explain in depth better where it all hooks up. I was confused, & the video helped a lot.

[@thoroughbreddiesel]

Glad it worked out!

[@G.I.JeffsWorkbench]

Great overview Wade. Definitely a must have, practical mod to every Powerstroke. In addition to the printer instructions, I also found S & S’s KZbin install vid. It’s 1 & 1/2 hours, so even slow learners like me should be able to install the kit.

[@thoroughbreddiesel]

Glad it was helpful!

You would think in 2022, that the designers and manufacturer of the CP4 pump would have solved the CP4 failure already!!!

[@ARCSSelfDefense]

You would think.....

[@LocoSOB]

How is Ford supposed to make money if they fix that problem?

[@lParohlx]

@@LWRC people still buy the truck at a premium price and then their motor-craft department keeps selling injectors and pumps making tons of money they love it why fix it

[@LWRC]

@@lParohlx What do they say about a FOOL AND HIS MONEY??!!! We landed men on the moon back in 1969 and yet in 2024, we can't solve a simple high pressure pump problem??!! Either Ford has incapable engineers or they're sandbagging and doing this on purpose!

[@NewOldSchool]

This should come on all stock.

[@G.I.JeffsWorkbench]

Yep, charge me more for the truck up front, instead of continuing to use a system that’s prone to failure. Reminds me of the aluminum wheels w/ steel valve stem corrosion issue. Waiting to see the outcome of the class action lawsuit, hoping to get proper replacement wheels on my dually.

[@joelcurtis1151]

If you already purchased your kit prior to the upgrade it’s going to cost you around 60+ dollars for the new filter housing + shipping , so around 80 bucks when it’s all said and done, and did you notice no o r said anything about the fact that one of the selling points and benefits of the previous kit was that you could see the fuel in the clear plastic filter housing

[@thoroughbreddiesel]

We said that in our previous video with the clear filter.

[@bellcats02]

Awesome job on the video

[@thoroughbreddiesel]

Thanks!

I installed this kit on my truck. It was very noisy so I contacted S&S through email. They told me it was normal and to check my hoses that that could be causing some of the noise. After driving a few days for work I got a major fuel leak. I had the truck towed to a local diesel shop. Ended up being my driveshaft seal in my cp4 was leaking. I had the shop check over my work and they installed a new cp4 and it blew out the driveshaft seal on it as well. We then took the S&S kit off and put on another pump and now everything is fine. I contacted S&S again they asked what seal in the cP4 and if I have a aftermarket lift pump. I have an air dog lift pump. After responding I got no response from them. Did I miss something are you not supposed to install these with aftermarket lift pump. I’m out a lot of money after putting this kit on did I miss the warning not to use if you have an aftermarket lift pump?

[@thoroughbreddiesel]

Aftermarket lift pump shouldn’t have effected this. S&S does a great job in responding to this so it may be wise to call them directly. If you need any assistance give us a call as well. 866 737 4966

[@gratefultrucker7781]

I don't think the after market lift pump would matter unless your lift pressure was way to high.

Hello Gelding Diesel!

[@thoroughbreddiesel]

Good day to you plant fairy!

[@tekshield]

Does that Donaldson Filter rust when water get's in it? I am asking because I have seen other videos that show those metal filters rust and then will send rust back through the system.

[@thoroughbreddiesel]

The fuel passes through two filters before getting to the high pressure system so we haven’t had any instances of that.

[@floydwilliams3321]

Very cool wade

[@chrishappysofar2090]

This filter system looks and sounds like the low pressure side returning to the tank and not from the pump to the injectors

[@F450FTW]

The failure happens on the low side, not the high pressure side.

[@rickeyketchum6671]

I’ve got the spe one on my 2016 do you think I would be better to trade it out for the S&s gen 2.1

[@Rabbitslayer257]

Im wondering the same thing lol

[@md1120]

With the new Donaldson filter you don't get a clear bowl to see the filtered junk, correct?

[@aversings7338]

Correct

[@vincetosto233]

Checked the Donaldson filter is only a 9 micron filter. Was wondering if you guys tried any other filters? Saw Wix has a 1 micron filter with matching threads/size, haven’t gotten my hands on one yet to check.

[@rvadventures]

I can't stand Donaldson filters,they have terrible customer service and cheap built filters that are over priced.

[@goldtooth10]

Whats the part number of that Wix? Lets see how the filtration efficiency numbers compare to the Donaldson filter, then we will know if it is suitable.

[@FRZNTYM1]

Will S&S Guarantee this DPK will prevent my fuel system from having a catastrophic failure?

[@thoroughbreddiesel]

No. But this product will protect your fuel system in the event that happens.

[@briancissell7737]

Where can you buy the filter on this kit?

[@thoroughbreddiesel]

Give us a call: 859-737-4966

[@videtosk]

Why not just use a Fuel Lubricant additive?

[@TaurenJam]

that's what i read, cp4 failure is due to low level lubricity coming from the diesel itself.

[@thoroughbreddiesel]

The fuel additive, although a good idea to increase lubricity and cetane, doesn’t correct the design flaw of the CP4.

[@videtosk]

It seems that the design flaw is in the design of the US diesel. No lubricity. I’m not hearing of many failures in Europe.

[@marksr1907]

I have the previous generation - can it be upgraded? Perhaps the filter body and filter? Any offerings on an "upgrade kit"?

[@MarsellusWallace2024]

What do you guys think of me adding a Dorman glass in line filter before this filter so I can see through to look for pieces of metal? If the pump is ruined but the shavings are being filtered, I need to replace the pump as soon as possible. A glass in line filter would let me check for particles. Can anyone think of a problem with doing this? Right now I still have the last model Racor style filter and I like that the fuel is visible.

[@thoroughbreddiesel]

We don’t suggest adding another restriction in the system, also return fuel temperatures need to be taken into consideration too. Change the filter regularly and cut the filter open looking for shavings.

[@diablokicks1]

With this revised kit (I have gen 2) you lose the ability to see if there are metal shavings in the return line. The alternative is to cut the filter open?

[@thoroughbreddiesel]

Correct. To monitor just cut the filter open. The plastic previous model was much more expensive to change and wasn’t as reliable. This is a little more hassle but a MUCH better setup.

[@korn111685]

The most important part of the title is “could”. Think about that people.

[@antoniodeperez1]

When is best time to install at what miles or let finish warranty I have 2020 f250

[@thoroughbreddiesel]

Earlier the better! S&S makes no claim that this product will not void your warranty, but it will save you a ton of money if the cp4 fails.

[@MarsellusWallace2024]

Do it right now. Worst that can happen is you replace a CP4 instead of your entire fuel system. If neither cost you money, they’ll CERTAINLY cost you time.

[@joshuagalchutt3483]

Just curious if this would void the factory warranty if I installed it. Pretty sure I'm not wanting to deal with this bastard grenading .

[@thoroughbreddiesel]

We have not heard of any dealerships denying warranty with this installed, but we cant speak for what some dealerships will do. If its in question, remove the kit before taking for warranty service.

[@bris9984]

I notice 2 or 3 small metal shavings when I change my bottom fuel filter is that normal or I have to get this kit?

[@thoroughbreddiesel]

If you find shavings, needs to be diagnosed as a failure. The bypass kit wont help here.

[@bris9984]

@@thoroughbreddiesel What need to be done to fix it?

[@thoroughbreddiesel]

Bring it to a mechanic for a diagnosis.

[@jakethesk8roberts763]

So does just running additive fuel every fill up not good enough? My cp4 was replaced before I bought my truck the first owner replaced at 75k now do they put the same dumb pump back in when they do that I don’t know if mine was upgraded or not

[@jakethesk8roberts763]

I have 156k on it now 2014 f250

[@JmF250]

The pump doesn't get upgraded, the kit separates the fuel going to the injectors from the fuel lubing the pump. If you don't have a big filter on the driver's side firewall, you don't have the kit.

[@thoroughbreddiesel]

Fuel additive is a good start, but not a complete answer to the design flaws of the CP4. Purchase this kit for protection!
