Wait... I'm confused. I thought this thread was about the 6.4. I didn't think the 6.4 had a Bosch system. I thought it was the Siemens 2 point high pressure system. Am I wrong?

You're correct. But the Siemens pumps had lots of failures just like the CP4's. It also took out the whole fuel system just like the CP4's.

Just Google 6.4 HPFP failure and read, read, read...........

Didn't read all 8 pages, but regarding the 6.4.... Ferd only made them for 3 years. That should be a dead giveaway right there. At lead the 6.7 is going on year #4 now with better reliability.
All trucks are awesome and all are a PoS. Just depends which ones are a PoS less days than the others.
Just put $2200 worth of new injectors in my Cummins with only 120k mi on it and I changed the fuel filter EVERY oil change. Big difference is I got new, not reman, 60 hp injectors AND a 2 micron filter setup for less than $2500 shipped to AK and could do the work in my garage in one day vs the $5k injector jobs I hear about on the Strokes. Oh and a valve adjustment for free before I buttoned it back up.

Ninerbikes if they do replace the pump are they upgraded? Thanks for you info. I should have said I could get bio but probably won't go to the trouble but who knows maybe I will change my view on that.

If your 2011 pump goes south, then yes, you will get the most current updated version of Bosch HPFP, with the latest goodies on it. Does it mitigate or solve the problem of bad initial design? Hard to say, Bosch is using every one of us as a beta tester.

Let's see how bad Gen 1 is when Bosch comes out with the CP 5.1 and 5.2 family of HPFP, and how long it takes before they cr*p out.

Can you be more specific about "what the latest goodies" entail!

Because the other two don't come with a never break down guarantee. When I drive by the Chrysler and GM service bays, I notice they are just as busy as the ford garage. No starving techs... now, if I was looking for a diesel, the rep of the cp4 would be on my mind, no doubt..

No no TV comes with a never break guarantee, but Ford seems to have issues bigger than GM with the Bosch HPFP 4.+ fuel pump. Keep in mind that Cummins still uses the 3.x HPFP.
I think if I owned a a GM or Ford with the 4.X+ HPFP I would be installing an after market filter and water separator, so what if Ford says that it will void the fuel system warranty Ford doesn't cover that anyway.

I have a Cummins Gen2 with a Bosch VP44 (AKA VP$$), I installed an aftermarket lift pump that supplies the necessary fuel pressure to protect the VP44. I also use a lubricity additive to help.

Meanwhile back at the ranch, my 6.8L gasoline engine keeps purring along. I never got caught up in the diesel fervor.

When human lives get lost and someone gets killed by a failed HPFP... the lawyers are going to have a field day with Robert Bosch with offering a HPFP that was not "fit and suitable for use" on north American D975 520 wear scar micron fuel. It's called fraud. Their pump requrements demand 460 micron fuel, America's fuel is 520 micron wear scar, not enough lubricity, yet they still brought the pump to market here in the USA, knowing the lack of lubricity in our fuel.

You've said this for how many years? It hasn't happened yet.

One could have said the same thing for the 6.0. Look how many complaints were made over that piece of junk. Nothing done. Nothing.

I remember years ago people were saying they were sure Ford was going to do the right thing and give them their money back on the hunk of junk 6.0 Ford sold them. They are still waiting..........and waiting........and waiting............................. Ford didn't need to do anything about it. Why? Because most bought a new 6.4 and got burned again!!!!!! And they had junk pumps too!!! LOL, Why do anything with customers like that?

I'm sure some will put on their grave stone: "Please give my family the money I never lived to see." :B

BTW, you might not like Bosch's products but guess what? What brand of fuel system does every modern diesel manufacture use? :B Much like Microsoft. :B

BTW, BTW, I'm not criticizing you for being pissed about the pump issue. Good for you for saying these pumps are junk, they are. It's just that IMHO it's not going to go anywhere. At lease you get good exercise.
