covered! always be critical and require evidence.

 

Gotta be honest, at this point, with my DPK installed, not really worried about coverage... if the pump goes, the DPK will save my fuel system, I'll buy the DCR pump and call it a day...

But for the non-DPK installed 6.7s, it might be a different story...

I'll watch the vid later.

 

Okay, watched the video and it was excellent... I should not have commented before watching. He makes a lot of good points. That said, I'm off warranty this December so I'm feeling good about finally getting my DPK installed "just in case." I hope I never have to buy the DCR pump, but if I do, I won't have to replace my whole fuel system also due to a CP4 failure.

I believe that video he references was posted here and I have seen it. It really sucks to have to go through that when the fuel system fails and it's not due to contaminants such as DEF, gasoline or water in the fuel causing corrosion on the parts in the driver's side fuel rail AND the dealer tries to bone you by not warrantying the repair... I wish the guy good luck and if this shows anything, it shows that having a DPK installed, even on a brand new 6.7, can potentially save you a hassle of dealing with a not so skilled and/or honest 6.7 Ford tech/service department. Plus the fact that you can still drive the truck with the failed CP4 with the DPK installed... especially for you guys pulling 5ers or pulling loads.

 

My take is if ford thinks they should disqualify a warrant becuase a part that was make with pot iron in stead of stainless steel gas rust ….they should instead explain why their water seperator doesn’t work or why their water in fuel light does not work. The folks with blown cp4’s are not saying “ my water in fuel light came on and I ignored it” or “ my water seperator was full and I only checked it after my cp4 failed”.


Ditto on the peace of mind due to DPK. I have an extended warranty and if my pump ever fails…I’ll just replace it my self.

 

I understand what ARod said as the part of the sensor that is outside of the fuel rail, past the threads which form the seal, can have rust on it but if there's rust on the part that's exposed to the fuel, which if water is present (and IMO, long enough for rust to form on said part), then it is not covered.

Quite honestly, if there's WIF for a few times, AND it doesn't take out the pump, that in of itself wouldn't be enough to form rust IMO. But if you are continuously using bad fuel, not using an additive to help with this (I believe K100 helps me even though I believe I'm buying clean fuel where I buy from) AND not checking the DFCM by draining some fuel in a glass or clear container to check in my case or in your case, by draining fuel from that big primary filter of yours and checking for water, then you will have rust on that sensor and be **** ed because you will get denied.

What amazed me was how well the S&S DCR pump handled that bad fuel and keep on chugging along which shows you can have a HPFP design that in worst case scenario, will not just fail and leave you stranded. But with that said, you still have to stay on top of the fuel you use.

My extended 7 year warranty will be coming to an end at the end of December this year, then I'm on my own but no worries with the DPK on now and the new DCR pump on the market now.

 

I posted the GSB on his page. I will post it here too.

I hate to break it to you fritz but using that B40 may have caused some pump damage...


From the GSB WK15 just posted....



Contamination Reference Table

Contaminant
Excessive Biodiesel (greater than 20%)

Symptom
Hard start, reduced power, poor drivability, low fuel pressure on low pressure and/or high pressure systems

Result
Premature high pressure pump and injector wear, metal debris, rust/corrosion, bacterial/fungus growth

Indicator
Fuel sample, waxing or gelling on primary filter, rust/corrosion on high pressure components


For your sake, and I'm hoping no damage brother... but maybe dilute the rest of it to B20 or lower...

 

If this particular part on the HPFP has rust on it, you can rest assured that the injectors have rust on them to and they won't be long for this world and will have to be replaced and good luck making injectors out of stainless steel. Water has been the enemy of diesel fuel systems for many years.

 

I didn't watch, but just to answer the question of the thread.
Nope.

Factory warranty 3/36 is expired. I have a Gold Certified warranty that explicitly states that fuel system problems are NOT covered. I have a DPK for this very reason and I buy fuel from high turn around stations.

 

That right there... once it's in, you won't worry about the CP4 blowing up... and now that you mention it, I'd have to go over my extended warranty and see if it does cover the fuel system components... stand by...

 

Pretty sure the Ford ESP when purchased with the truck covers the fuel system. The Certified plan though does not. The ESP and Certified are quite different from each other. The B2B is 12 month or 12K miles and works like the factory warranty, including fuel system, but has a deductible. The rest of the plan covers the powertrain for 7 years or 100K miles but explicitly states NOT the fuel system.
