EcoDiesel Z96 HPFP Recall - Parts Available

[Diesel85]

The Z96 High Pressure Fuel Pump (HPFP) Recall has started on the RAM 1500 EcoDiesel trucks.​

The new Bosch CP4 HPFP part numbers for the RAM 1500 EcoDiesel are as follows (at time of writing):

CSSMZ461AA -- Warranty/Recall Part Number (AKA: Recall/Warranty Campaign Kit)
68631088AA -- Standard Part Number (AKA: Purchasing at the Mopar Parts Counter for cash/card)

You will get either an email or a letter in the mail, or both notifying you that the part is now available and to schedule time with a RAM dealer to get the HPFP recall completed.

Note: Once the new HPFP is installed, a label on the fuel door will be placed, stating no more than 5% biodiesel (B5) is allowed to run in the EcoDiesel. There will also be a placard inside the vehicle after the technician completes the recall stating this and other information.

Attached is the part number confirmation and a copy of my recall parts ready notification (with me and my trucks information redacted).

Once the technicians documentation on the recall repair process is made publicly available, I will post it.

Aren't there states that have B20 as a standard at the generic pumps?

I'm not quite sure about that. However, I'm sure someone will chime in.

The closest place that sells any grade of biodiesel is 2+ hours away from my house.

Just not popular in my neck of the woods I guess.

But I'll take a moment to rant. I'm not happy that after replacing the HPFP, it is essentially gelding my truck from what I originally paid for it to do... it's essentially gelding it from running on B20. It's a bait and switch tactic in my opinion. /rant off.

Yes, and it is weird too as Bio has the better lubrication properties then Dino.
Just slightly less BTU.

Like said, weird move from Ram to ban that fuel.

Yep. Even well known folks (not mentioning any names) that deal with tuning EcoD's are surprised for that very reason.

Likely the reason why Cummins rolled back and stuck with the CP3 to keep the B20 status.

I have a feeling the (revised) CP4 is coming back to the Cummins due to tightening emissions down the line.

Maybe it is because of the viscosity in cold weather use, there is quite a difference between the two. Cold starts in winter before the fuel heater really kicks in.

I recall SoCal has a high Bio requirement... In Minnesota, No. 2 diesel must be blended with at least:

• 5% biodiesel from October 1 to March 31
• 10% biodiesel from April 1 to April 14
• 20% biodiesel from April 15 to September 30

So does that mean I can't use my EcoD in Minnesota between April 1st through September 30th?

That is a question only FCA can answer being the amount of Bio mixed in with diesel is mandated by law in MN and I'm sure their are other states that have a Bio mandate higher then 5%....

It's odd that NYS doesn't have a mandated biodiesel mix law. From doing hours of exhaustive research (prior to this), I found that no one except the refineries really know what the true percentage is of the pump diesel.

Where I'm pointing to, is if an owner has a fuel related issue with their truck, I can see Stellantics trying to weasel out by stating the owner was pumping in higher than B5. Without an in depth fuel analysis, an owner isn't going to be able refute that unless they keep receipts. Even then, who knows whats in the pumps at some of these stations.

I thought the EPA mandated that all new diesel engines must accept B20 sometime in the 201X's. But I can't seem to find anything, so it might not be a regulation.

For now, I'm personally not going to do the recall, and my truck is running fine. To me its a new fuel pump (and system if it goes bang) down the line if I keep the truck, and I can still run B20 under warranty.

More then often I see the label at the pump stating - may contains Biodiesel up to 20%. Many many places with that label.

As I have been told that label is used as a CYA or in places that like MN where the amount of bio can vary from as low as 5% up to 20% depending on the time of year, so you never know what your bio amount your buying unless you ask, then you hope the person you ask has a brain to know where to look for the answer or who to ask if they don't know the answer

I'd say they have NO clue behind the counter what's down there in the tank.
That's me, expect the worst, so they can always make better and surprise me in a positive way.

Like I said earlier, the amount of research I've done, really confirms that ONLY the refiner knows what is actually going in those tanks.

FYI Bio is mixed into the delivery tanker while its being loaded at the tanker loading dock, the refiners have no clue what the bio amount is being loaded in to each tanker before it heads to the station for delivery....

I've read that too, but some say refiners mix it in and some say at the loading station.

At the end of the day, it makes me concerned not just for my truck, but others, with the type of fuel. And the fact that folks paid for a truck that is supposed to take up to B20.

The only reason I know for sure that things like Bio & Ethanol its mixed at the loading doc is until a few years ago I had cousin who drove tanker truck for 8 years delivering fuel to gas stations & truck stops all over the state of Iowa...

So… Does anyone know what changes were done to the Cp4 pump or is it a pump from another supplier like GMC went with? I know Bosch made some major changes the failure rates in ford products have dropped way off according to my friends that service ford trucks.

No idea until someone buys one from the parts counter and does a tear down analysis. Or somehow gets one from a totaled truck.

However, from what folks have said, it just has harder internals. I don't think they pinned the lifter bores.
