Seen SPE has a CP4 disaster prevention kit for the 6.7. I’m for all safety measures in place to preserve my Power Stroker, so has anyone installed one and what are your thoughts?
Agree with everything you said. Air in the lines is another major cause of cp4 failure.Just a few things to think about...
The idea of catching metal from the hpfp if it grenades is fine and dandy. The problem with these kits comes down to what causes the hpfp to go kaboom in the first place. Generally that pump is damaged by some kind of fuel contamination (Gas, def, or water) or lack of lubrication. They really dont just come apart on their own all that often (Yes, it does happen but its not as common as you are led to believe) and the things that damage the hpfp also damage your injectors...
I dont see any harm in adding one of these things, but dont look at them as a fix to anything. If you let your brother/friend borrow your truck over the weekend and he accidently fills the 1/5 of a tank he used with gas... You may not know much about it for a few months till the pump starts coming apart(And at the same time, we have seen trucks suffer little to no damage as well). And unfortunately, your injectors have been subjected to the same lack of lubrication. Or that whine from the lpfp that you ignore for a month till you have time to let Ford have your truck... Or the 30k miles the previous owner let the same fuel filters sit in there (doesnt just cause issues with debris, thats a fuel pressure problem)........... These kits dont save your fuel system from that abuse. If water gets through, you are still screwed... Injectors, inside of lines, connections... Everywhere there is steel will corrode.
If a pump comes apart, I dont know any sane mechanic that is going to confidently tell a customer that this kit saved their injectors unless they are 100% sure there has only ever been clean, dry diesel through that truck.
Just my 2 cents.
CP4 disaster prevention kits supposedly reroute the fuel back into the fuel tank rather than pushing it through your fuel lines, rails, and injectors. When you have a CP4 failure, the metal shavings will still go into the fuel tank so that would have to be dropped and cleaned out and so would the return fuel line and fuel filter on the tank.i still fail to see how it will prevent catastrophic failure.
The point of the prevention kit is that metal shavings don’t go to your injectors. This is the premise of how these kits work.Idk, i feel if debris has made it through the cp4 and injectors, it going to the fuel wont make a difference at that point.
I also really like that its the only one with a filter that comes right off the cp4 pump to catch a failure so you can easily checkI have been doing a lot of research into SPE Diesel, they seem like they do there research and testing before they throw something out. I have one of there Disaster prevention kits on order. I like theirs over everybody else because with theirs you don't have to cut a line, everything uses factory style connections, so if it don't work or you want to put it on a different truck you can easily.
