2019 Cummins Rough & Tumble Idle After Morning Start Up. What could be wrong?

[nlambert182]

That's about the only way you can guarantee you get OEM filters. Do not run aftermarkets. These engines do not like them. Geno's or direct from a Mopar dealership.

90% of the Mopar/Cummins filters on Amazon and eBay are counterfeit.

If you want to buy true OEM for both:

Mopar front filter - 68157291AA
Mopar rear filter/separator - 68436631AA

FleetGuard (owned by Cummins Filtration):
Front filter - FS53000
Rear filter - FS20378

Thank you, sir.

I buy mt filters from Genos.
I use a injector cleaner additive about 2 x per year. Don’t know if it helps but makes me feel better. My truck idles and runs smooth with almost 60 k miles.

Fuel filters changed 13,000 miles ago, so still within service.

It's good to know then, it's not the DPF

Ok so 13K but how many months? Service interval for both fuel filters are 12 months or 15K, My go to is Cross filters for the front Fleetguard filter FS53000 being the price they list includes shipping to your door and Rock Auto for Rear filter then Genos Garage, I check all 3 places to see who has the best over all price as sometimes one is out of stock when the others still have filters to sell... The only other filter I would trust for rear fuel filter is the Baldwin PF46152 but to get a good price on it ya need to shop around being I have seen it priced higher then Mopar filters..

Here is another place to get the FS20378 rear filter at a good price: https://klmperformance.com/products/fleetguard-fs20378-fuel-water-separator?variant=50433907786008

I never go by the months as that penalizes those of us that drive less than 15K miles a year, The clock does not deteriorate a fuel filter.

Ya should if you want to be in compliance with and keep your warranty requirements happy, but no way would I personally go beyond 24 months on the front filter 12 on the rear. BTW yes time does affect the filter media or so I have been told/ preached too for the past 20 years for diesel filters....

Whoever preaches that time deteriorats filters also says oil goes bad after sitting on the shelf in a bottle for 2 years. Was perfect under ground for 20,000 years. There is an awful lot of nonsense strictly designed to sell more. Just like an expiry date on honey. They have found jars of honey 3000 years old that is still perfectly good. Doesn't stop them from putting a 1 year expiry on packaged honey today.

Don't believe everything you read.

I also run Archoil Diesel additive on every fill up

Correct, sir! Thank you! A filter is NOT a perishable item like milk or cottage cheese.

My extended factory warranty on the truck expires in Jan, so I'm not worried about that.

Since we aren't using unrefined oil out of the ground...

EXPIRED: When Does New Oil Go Bad?

If you are like me, you probably have a several bottles of "new" oil in your garage, but they have probably been there for a while. Like a gallon of milk in ...

You do you, but I'd rather my additives package not be sludge in the bottom of the bottle.

Doc's Diesel fuel filters are made in Taiwan

This picture is from another forum but it's of a Doc's Diesel fuel filter for a EcoDiesel

Per the owner it plugged up and blew out in under 15K miles.
This filter doesn't look like or is built anything like the OEM version.
OEM version:

Sure glad I cancelled that Amazon order for the "Doc's Diesel" filters. I emailed them asking where these filters are made and this was their reply:

You didn't really expect them to say: We understand why you would cancell. We sell absolute crap that is made in Taiwan with zero quality control. Would you? Even though that is the actual truth. -

I don't want to jinx you and I hope its not the case but.....
Check for soft codes (no light but a code will be stored Pending) using a quality scanner or AlfaOBD. If you see any misfire codes you MAY have a lifter failing.
With your service habits and driving characteristics, you're a prime candidate.
If it is a lifter you MAY hear it on cold start up and it will eventually throw a hard code & check engine light for the particular cylinder misfire.
Hope that's not the case with your warranty running out in January but now is the time to figure it out if it is a lifter going bad so the dealer replaces it on their dime.
This is the problem with the 2019+ trucks, the hydraulic lifters, and is why I'll probably keep my '18 for a long time.

Let me see if I got this right, your saying that fuel filter media does not deteriorate or that the media is not affected at all after sitting in diesel for 2 years?

If the filter media is affected AT ALL, by diesel fuel itself, then you are buying the wrong filters. If diesel breaks down the filter then it is a source of contamination that it is supposed to stop.

No I'm not buying or using the wrong filters, I buy an use either Fleetguard or Mopar fuel filters, running one longer than 24 months is twice as long as what Cummins states they should be used for and too me using one longer than 24 months is 2x longer that what was told/taught by older HD Diesel mechanics with 20+ years of experience along with other people I have learned to trust over the past 20 years... Any way you can run your filters longer if you like, my self I will not risk a $20+K fuel system just because I was to cheap to spend $120 a year on fuel filters...

I am almost 70 years old. I have owned hundreds of vehicles of all makes and kinds. Many I have put as much as 300 thousand miles on. A couple of diesels I ran to 700,000 miles. In all those vehicles I have never done a motor, transmission or other major repair. The only vehicles, motorbikes or boats I have done major rebuilds on are ones I was racing or using in some other competitive, severe duty way.

You do whatever makes you happy and if changing out perfectly good parts gives you peace of mind, it is your money. After all the experience I have had, I am just trying to pass on what I have learned. This many vehicles, this many miles and this much time racing, the results aren't just luck, even if it doesn't match current conventional internet lore. Use it or not, no difference to me.
