Bosch CP4 Fuel Pump
Is Ford still using the Bosch CP4 fuel pump in the 2020 6.7 PowerStroke?
I know there is a class-action law suit involving this fuel pump.
ALSO, that same pump failed in my 2011 F250 6.7.at 59,000 miles.
I'm lucky I heard it making a whining noise and had it replaced before causing Major Damage.
It cost me $1200 to replace.

The "Lift Pump" is on the frame rail with the fuel filter as part of it. The HPFP is mounted on the front of the engine. The lift pump is approx $650 to replace it.

I understand that, Larry. Replacing the HPFP CP 4 for $1200 seems like he found a real bargain Was why I was asking him.

OK Guys.
I dug out my invoice from Babbitt Ford, Flagstaff, AZ.
I thought $1200. Actual was $1330.70, parts and labor.
The description says, "Replaced Primary and Secondary Pump and Filter and Electric Fuel Pump. Added some MERC-V to filter to prolong fuel system"
I don't totally understand all of it, but the Whining I had was coming from the unit bolted to the frame towards the driver's side rear.
Any further comments would be greatly appreciated
Thanks, Phil

That's the lift pump. The CP4 is on the engine.

Thanks for that info.
I now have almost 10,000 miles since the lift pump was changed. Everything seems fine.
Hopefully it stays that way for a year or two. I'm planning to trade up to a new, or fairly new F350.
THANKS AGAIN, Phil

There are sellers on eBay selling the CP4 for 700 to 800 with no core. One says it is OEM pump new not rebuilt.

One of the main reasons running a newer Ford would not be my first choice. Not commercially anyway. '18 or older RAM still used the much more reliable CP3 in the Cummins. Notably RAM switched to the CP4 in the 2019+ Cummins motors and therefore would not be my first choice either. This couldn't have been anything other than a cost saving measure.

Hard to say how widespread it is. Even brand new 2020 Rams with 40,000 miles are having them blow up and cause 15,000 dollars in damage. I would religiously run a lubricity additive like Opti-lube or similar in every tank if I had a truck with one of these in there.

CP 4 ---> Pre-Planned Product Failure (Replacement), problematic, cheaper to manufacture than (more reliable) CP 3
Fuel issues will (and do) take out the CP 4's metal to metal cam-roller arrangement in a New York Minute. Shrapnel / debris goes everywhere post failure too...

Most tend to use a lubricity additive with their trucks since we all know that after the Feds lowered the sulfur ppm content of ULSD that lubricity for the pump was lost.
Just remember, a forum in a microcosm of the real world. Problems listed in forums are usually not representative of the real world and the 6.7 engine. Forums tend to amplify a problem only for the members of a forum.
