I have searched as much of the internet as much as I could handle then called Donaldson dealer/Cat dealer, to hunt down info, numbers and sizes for your stock or aftermarket Cummins.

Have to say they were both very patient with me not being a redistributor or even as wholesalers and asking a million questions to basically get this information to whoever wants to read it.

Donaldson & Caterpillar both have two version of each filter a regular version then a higher efficient version, with Donaldson its White then Blue (the physical colors of the filters) with Cat its AHE then UHE (Advanced then Ultra) since both Cat filters are yellow.

Start this right off for a stock system, you have three filters Oil & two fuel filters, neither Donaldson or Cat makes a factory style front fuel filter under the hood (cartridge) that would show up in their system that was guaranteed to work.

Oil Filters, Donaldson Blue is pretty well known here and across the web the ELF7349 now known as the DBL7349 (I personally run this filter) , the Cat version is 396-4596.

Now the factory rear water separator filter Donaldson P551833 this is a blue filter the Donaldson rep told me however water separators only come in white but this is equivalent to the blue, Cat does not make a stock water separator.

So for stock front fuel use factory or favorite aftermarket, oil DBL7349 or 395-4596 then rear either stock or P551833

Onto the aftermarket what everyone wants to read.

You decided you really don't like your front cap/cartridge fuel filter either you broke it or stripped out the cap, so you replace it with a spin on filter setup.

These aftermarket kits mostly come with a standard 1R-0750 Cat filter, while a good filter according to filtration tests over the internet from what I can find and talk to the manufactures, this filter and the next three (749 -1313 - 1319) performs slightly worse then stock.

These next three filters for an aftermarket application if only running two filters I would skip are the Cat 1R-0749 (same as the 750 just bigger) the Donaldson P551313 (same as 750) and P551319 (same as 749 Donaldson bigger version of 1313) all three of these filters are fine if you plan to run a secondary rear filter so basically three filters.

Now the filters I would run if you are only running two filters if you either don't plan to add a rear one or change the front to spin are Donaldson Blue DBF5814 & DBF5817 then the Cat 319-0844 & 416-1225 (rep told me 1225 is really well known and liked) if you have the space I would personally run the bigger filters the 5817 or 1225 more surface area, but everyone setup is different.

Last if you are running an aftermarket water separator, this was kinda tricky as we just used info from a couple kits then cross reference since most water separator kits use a thread group of 1-14. Would appreciate if anyone has anything to add here the most since this info was the hardest to really confirm.
Cat does not have a UHE version of a water separator. Lets get on with it.

Donaldson P550847 then Cat 179-2949 (this is probably the most well known water separator the guy from Cat said.)

The bigger version are Donaldson P551000 & Cat 256-8573
Donaldson blue versions P553203 (Old SAE version) P553213 (New ISO version)
Last is the big version in the Donaldson Blue P550901
If someone could confirm the water separators that would really help as most of the info was just based off of popular aftermarket setups.

For those who want easy to read condensed version
Stock Oil - DBL7349 or 396-4596
Front fuel stock cartridge, just use stock filter.
Rear fuel stock or Donaldson P551833

Aftermarket front spin on without adding a rear third filter - Small DBF5814 - Cat 319-0844 - Large if you have the room DBF5817 or Cat 416-1225.

Rear aftermarket fuel filter spin on or otherwise known as front filter relocation. Same setup Small DBF5814 - Cat 319-0844 - Large if you have the room DBF5817 or Cat 416-1225.

My personal vehicle has an added rear fuel filter setup, then I plan to delete the front fuel filter when it comes time to change my filters, I am going to run the DBF5817.
