I've thought about this as well. I'm at 105,000 and no problems yet. I am going to put the S&S disaster prevention kit on.
It seems like if you buy good fuel and run an additive, the likelihood of failure goes way down. |

Pros - Will not nuke itself and cost you $10k in fuel system repairs. DCR puts out 25% more fuel to the injectors. DCR bolts right up with no modifications. DCR has fewer moving parts.
Cons - Price. $2k seems crazy high to me when considering most people have to hire someone to do the work which will add to an already inflated cost. I’m at the crossroads now… she’s got just over 200k and runs great. CP4 does have a disaster kit installed but even those aren’t fool proof. Do I keep it and install the DCR or face the prospect of upgrading to a newer truck with fewer miles with a DCR installed? |

Pre-ordered one and it’s been sitting on the shelf since last summer-ish. If I have a catastrophic failure before I get around to installing it…

Thanks guys.
My truck has 125K miles and has shut down on me a few times. The thing runs fantastic.... until it shuts off. This happens when I get into it. Once while towing and climbing a mountain. Computer hook-up shows low fuel pressure. We believe this thing will cure the problem for good. |

Quote HistoryOriginally Posted By tree-hugger: Short answer: Yes. What are those other things? I can use all the help I can get! Any metal in your fuel filter? Have you done any other mods to your truck? Had any bodywork done on the truck or has the bed been off? Some of the things that come to mind: Water in the diesel Fuel rail issues A kinked fuel line Clogged fuel filter Bad aftermarket fuel filters/damaged or miss-sized o-rings Anything else that could be causing cavitation in fuel supply or backup in return Electrical issues to go along with anything in the fuel system The CP4 is absolutely the weak link, but it is far from the only thing that can go wrong. That said, dropping $2k on a part without knowing that is the issue may not feel good when your truck still dies going up hills. |

But you still have the expense of the kit and the install. Then if you end up needing it, you’re more money into another pump. And then you’re doing another install. For me the DCR made sense because I am also wanting to tune it. |

Not the case? If I recall correctly, mine is a gen 1, and with a bit of research, they were susceptible to allowing some metal through although not as bad as one without the kit. Thus far I'm reluctant to drop $2k on a pump, plus mechanic fees since I'm not a diesel tech, I just play one on arf. |

Version one isn't guaranteed to catch everything. The new version sends the fuel through a filter and supposedly works better. I haven't bought one yet, but I have yet to find someone who has needed one of these yet to ask how it worked. |

I need to get the disaster prevention kit. Mine's a '16 and stock down the paper air filter with only 65k, but the pump just seems to be a time bomb.
The conversion seems to be a decent fix from doing some reading about it |

These are a known weak point and if they fail, your stuck on the side of the road. I bought the S&B version, and it's nice. |

Thankfully I was able to limp it home and the local oreillys had one of the Dorman replacements in stock.

I did lose the cold side charge pipe. Got a silicone/kevlar one from smeding diesel. Truck was not happy when that popped. Been a great truck. Especially after fixing the exhaust. |

I’m kind of new at this stuff but I’ve read a lot of posts on the TDI forums saying to stick with b5 because supposedly it adds to the lubricity of the fuel and helps keep the HPFP from self-detonation.
There is also a disaster plate for the TDI’s available and it ain’t cheap. My mechanic says if it goes he will charge $4,700 to clean all the parts out of the system and replace the pump. This is on the 2.0 CKRA. I’ve read that Diesel fuel with 1% gasoline contamination is all it takes. Therefore, I always fill up at half a tank to mitigate that risk. You never know when some trucker f’d up and put the wrong hose in the wrong place at the station. |

You never know when some trucker f’d up and put the wrong hose in the wrong place at the station. I don't think you are mitigating anything by filling up at half a tank. Nothing wrong with it, so if it gives you peace of mind, fine. But that's kinda nonsense IMO. I've heard of lots of different horror stories, but never one involving the fuel delivery guy dumping the wrong product in the stations tanks. That is such an outside chance it is not even remotely worth worrying about. And if they ever did that somebody would be paying for your new fuel system and any other affected components. And they would not try to wriggle out of it either. Totally cut and dried situation. Might take a minute to get it handled, but it would be. The main thing you want to do is use a station with high fuel turnover. That's pretty much it... |

Once while towing and climbing a mountain. Computer hook-up shows low fuel pressure. We believe this thing will cure the problem for good. CP4's have a very low failure rate in Fords. Anything to the contrary you read is just forum experts regurgitating stuff they read online. I am a ford senior master and have done in total exactly 1 high pressure fuel system that could not be attributed to neglect and was actually covered by warranty. The most common thing i see that shows low side fuel pressure is. 1. Homeboy changes his own fuel filters on the frame mounted era fuel pumps and doesnt get it tightened all the way because the threads are all packed with dirt. 2. Fuel system contamination. Usually def, sometimes water. It will cause pump failure or problems with the VCV or PCV and register as a low side system code but it usually has low/high cranking pressure codes associated with it as well. 3. Somone uses a fuel additive or cetane booster and the cardboard gasket from the lid gets stuck to the spout and they dump it in the fuel tank and clog the pickup. When they shut it down it drops away from the inlet and may go hundreds or even thousands of miles before it happens again. 4. A concern with the PCV or VCV. Usually the PCV because they are kind of finnicky to install. 5. An injector with a stuck open return. Replacing a CP4 out of concern is pants on the head a waste of money. |

Odd that you consider it a very low failure rate part when nearly 100% of them fail before 200K miles.
They just don’t get fixed at the dealership because they’ve long since been deleted to get to that many miles. |

I have a stock 2015 F250 and everything I've seen has been around DEF/water in the fuel. If that isn't true, I'd like to know.... |

I work in ag, Ford diesels are the most common truck here.
Emissions problems, death wobble, and CP4 failures happen to almost all of them. A friend of mine has a very successful shop that specializes in diesels and will tell you the same thing. It’s not if, it’s when it goes out. |

Quote HistoryOriginally Posted By tree-hugger: Death wobble? It's where the truck will unexpectedly vibrate wildly as the steering wheel goes back and forth rapidly. It happened to me once at 60 mph. I hit a bump and by the time I regained control, I had moved from the center lane to the right shoulder. Ford did modify something in the steering and it hasn't happened again. |

Death wobble is usually due to worn components. You may not see it with just a little bit worn tie rod end, but 2 tie rod ends with play, along with some ball bad ball joints in your knuckle etc., will get you death wobbling and hanging on for dear life. I think most of the time worn components can be diagnosed and replaced, but every once in a while guys struggle getting it under control. If you just shotgun method parts at it, it's about like anything else on a vehicle, you may or ma not get it.
Every once in a while it's just an inherently shit design that helps it rear it's head, looking at you Dodge with your y-style steering. |

Fords will death wobble from brand new. I had a ‘19 F250 that did it in under 2K miles. My business partner had a ‘20 that did it enough times inside of 8K miles that he traded it off.
Trying to push the front axle with rear mounted radius arms is just a bad design. |
